Inquiry](https://celestavia.com/en/main/#government) [Contact](https://celestavia.com/en/contact/) CELESTAVIA · Suriname · From the Paramaribo river front to the coast, the plantations and the interior # The elevated, flood-ready transport network that joins **Suriname** **Celestavia is an elevated transport system:** electric carriages drive along two large suspended steel ropes per track (four on heavy-cargo lines). The carriage moves, not the rope — it is not a cable car and not a power line. An electric, automated network above the traffic, the flooded streets and the soft coastal clay. It joins Paramaribo, the airport, the port, the river towns and the rice and mining regions, carries the country's fibre and early-warning sensors, and keeps moving people and goods when heavy rain closes the roads. 541 km network Cabins run in 136 km/h gusts, above the floods (simulated) Investment US$ 1.80–2.27 bn (raised halls) / 1.83–2.30 bn (domes), simulated Executive summary The film Operating in extreme weather Flood-safe depots Rescue system Fibre, 5G and sensors Rain and floods Coast, sea level and soils Diagnosis Tourism The network Peak hours and tracks Megastations and storage Live without a car Ports and cargo Power Investment GDP and jobs Compared with other systems Whole-country programme Schedule Contact A self-initiated document. Celestavia prepared this Suriname profile on its own account, from Surinamese and international public data and from its own simulation platform. **It does not derive from any plan submitted by or to any Surinamese authority**, and it has not been discussed with the Government of Suriname, its ministries, the port authority, the power utility (EBS), the disaster-management office or any district commissioner. Every result is simulated at profile level, and the alignment, phasing and amounts are subject to the Phase 0 feasibility studies. Where a choice is still open, such as the power source, the carriage classes or the unit prices, the costs are shown as ranges. Celestavia's role: it designs the electronics and software, does the conceptual engineering, and promotes and aggregates the technology. Towers, carriages, cabins and buildings are contracted to others: car makers build the carriages and cabins as series automotive parts, and local and international contractors build the towers and stations. ## Executive summary 541 km9 lines in three phases 3 + 248megastations and stations ~100,000riders a day at the design year (simulated) < 10 minwalk-in wait at a station (simulated, typically a few minutes); with the reservation app, no wait at the station 136 km/hgusts passenger cabins keep running in (simulated) - **The solution: a second layer above the roads.** An electric, driverless network of 9-seat cabins and light 2.5-t cargo boxes, running on fixed ropes over towers about every 85 m. It starts where Suriname moves most, Greater Paramaribo, and grows along the coast and inland: first Greater Paramaribo's four metro lines and the airport line, then Nieuw Nickerie, Albina and Paranam, and later Afobaka. - **No traffic, no waiting for the minibus.** Book by app and there is no wait at the station: the app gives you the nearest available departure; walk in and the wait stays under 10 minutes (simulated, typically a few minutes), day and night. Blauwgrond to Anton de Kom University in 27 min (simulated), against 31 by road at the peak; the centre to the airport in 56 min, about as fast as the road (54 min), with no traffic jams on the way. - **Above the water.** Heavy tropical rain, flooded streets and swollen rivers do not stop a line that runs over them. Towers stand on piles driven through the soft coastal clay, and stations, substations and depots are raised above the design flood plus an allowance for sea-level rise. In a flood the line becomes the way out: up to **10,000–39,000 people an hour** across the network. - **Passenger lines that also carry freight.** Every line is a light line: passengers ride the cabins, and food, parcels, retail supplies and waste ride 2.5-t boxes between 6 distribution centres, the Nieuwe Haven, the rice country and the supply routes to the interior. Heavy ISO containers would ride only separate heavy lines, and only where the flows justify them. - **A national backbone for data and early warning.** Fibre, 5G (6G-ready), cameras and rain, river, tide, wind and lightning sensors on every tower, shared in real time with the meteorological and disaster services. **Every tower has its own battery backup for at least 21 days of total power loss**, so 5G, sensors and cameras keep running through a flood or a blackout. - **Live near a station, no car needed.** As the network grows, more families can live without the cost of owning a car: see living without a car. - **Investment of US$ 1.80–2.27 billion with raised depot halls, or US$ 1.83–2.30 billion with raised domes**, for the whole network on 1.5 kV DC traction (simulated ranges that hold eight in ten draws of the unit prices; the depot type is subject to further study, the power source is open, and no supplier has quoted yet). Construction adds up to 2.2 % to GDP in its peak year, with about 1,600 permanent jobs. We state the economic case plainly: the simulated benefit-cost ratio is 0.25 (0.04–1.03), and the levers that improve it are listed. - **A whole-country programme:** the full food chain from soil to table and back with Break-Thru Technology, beyond-organic agriculture, education for the AI age, integral health, local industry and commerce, and tourism from the historic inner city of Paramaribo to the plantations and the rainforest. ## The film: solutions to today's transportation problems An electric, automated network that runs above the traffic and above flooded streets, from Greater Paramaribo and the airport to Nieuw Nickerie and Albina, carrying passengers and freight, with fibre, 5G and sensors on every tower. The film presents the simulated network, its small walk-up stations, flood and squall operations, power, schedule and investment ranges. *Coming soon: in about 24 hours we will publish a newer version of this film, with more realistic images and updated figures.* Every figure in the film is marked as data, simulated or projection; results are simulated and costs are given as ranges. ## Operating in extreme weather: full, partial, secured, rescue Suriname lies south of the main hurricane belt, and its extremes are different from the Caribbean islands': long, heavy tropical downpours in the two rainy seasons, rivers and swamps that rise over the roads, spring tides on a low coast, sudden squall-line gusts, frequent lightning, and soft clay that will not hold a shallow foundation. Celestavia's carriages do not hang from a single moving haul rope like a gondola. They roll on fixed, tensioned track ropes, two per track on light lines, held by lock rollers, high above the water. Our simulation platform computed, for every vehicle and every wind speed, the roll of the cabin, its sway toward the other track, the unloading of the windward wheels and the loads on ropes, towers and piles. The result is a five-level operating plan, triggered by the forecast first and by the measured gust, rain and water level at the tower sensors second. Figure 2. Operating levels by 3-second gust at the towers, with flood service (simulated). LevelTrigger at the towersWhat runsWhat stops **0 · Full operation**3-second gust up to **111 km/h**, in any rainEverything, at line speed: passengers and light 2.5-t boxes.

In a flood, the line switches to flood service: evacuation runs from flooded districts, and supply cabins with water, food and medicine.Empty cabins stowed; open-air platforms cleared during close lightning, boarding under cover. **2 · Evacuation and stow**gust 136–151 km/h, or from a severe-weather or tropical-storm warningEvacuation runs to shelters on high ground, then every unit rolls into a flood-safe depot.Regular service and cargo. **3 · Line secured**above 151 km/hNothing moves. Ropes, towers, piles and the fibre ride out the event alone, designed for a **242 km/h gust**. Suriname has no national design wind speed; the reference is the 169–184 km/h that building codes use in thunderstorm regions, and the design is far above it.All carriages and cabins are inside raised, storm-rated depots. **4 · Rescue and recovery**after the event, gusts back below Level 1Tower cameras and drones inspect every span; battery rescue carriages run; the line restarts section by section with proof runs.Any section not yet inspected. The worst conditions at each stage (simulated) #### Fully operational The whole system runs at line speed in gusts up to **111 km/h**, and in the heaviest tropical rain. The line is guided, automated and above the water: a street under half a metre of water, which stops cars and minibuses, does not reach it. #### Partially operational **Passenger cabins keep running in gusts up to 136 km/h**, beyond the strongest squall gusts recorded in Suriname (95 km/h). For comparison, urban gondolas stop at 57–90 km/h, and metro and bus systems typically stop at 56–113 km/h. This is the window in which Celestavia carries people out of flooded districts: up to **10,000–39,000 people an hour** across the network. #### Secured: built far above the storms With no vehicles on it, the line is designed to survive a **242 km/h gust**. The deeper piles and stronger towers for the soft clay and the design wind add about **US$ 168,000–574,000 per km**. The whole fleet is inside its depots in **3.9 hours** (under 4 hours: in the megastation depot floors, Paramaribo Centrum 9 berths; Latour 13 berths and two entries a side; the airport 8 berths), or **8.4 hours** after a period of evacuation service. #### Rescue: the first thing back When the water or the wind drops, battery rescue carriages leave every depot: **323–351 km** on a swap-size pack with the grid down, carrying ambulance, rescue and supply cabins over flooded or blocked roads. The line's own fibre, private 5G and power feeder can serve as an emergency backbone. Every tower has battery backup for at least 21 days of total power loss. All thresholds are simulated at concept level with placeholder drag coefficients, gust factors and comfort limits; they will be confirmed by wind-tunnel testing, geotechnical investigation and detailed design. Speed limits within each level are operating policies. Comparison limits for other systems are from published operating rules collected in our hazard research. ## Flood-safe depots: raised halls, domes and megastation floors A network that is designed to stop must also have somewhere safe to put its fleet. On a low coastal plain, that place must be dry. The simulation placed a raised, storm-rated depot **every 30 km of line — 20 depots** for the 541 km network — and timed the stow of every carriage, cabin and box. The fleet needs about **49,000 m²** of protected floor, set at least **2.6 m above the ground**: above the design flood, the spring-tide level and a sea-level-rise allowance. #### Raised hardened halls The standard depot: a reinforced-concrete hall on a pile-supported platform, with safe-room-grade roof, walls and doors. It parks most efficiently and doubles as a maintenance base: **US$ 121–291 million** if used throughout. #### Concrete domes on raised platforms Monolithic reinforced-concrete domes, a form with a long record in extreme winds, built on raised pile platforms where the ground is softest: **US$ 145–368 million** if used throughout. #### Inside the megastations At the three megastations, a depot floor inside the building, above street level, saves land and serves the station: **US$ 48–122 million** for the depot share of those buildings. #### How the fleet gets in As at our megastation design, the line's ropes end at an anchor tower outside the depot and the units roll in on battery along internal rails, so no rope passes the door. A sliding door rated for wind pressure and flying debris closes at Level 3. Every depot floor is raised above the design flood, and every depot keeps its access by the line even when the streets around it are under water. #### Shelters for people, too Each depot can add a people hall the size of its vehicle hall, a separate fire compartment: about **27,000 people** across the network during an event, or 14,000 for multi-day stays. Between events the same halls store water, food, medicines and charged battery packs. Every battery sits in a fireproof container with its own fire-suppression system. Figure 3. Time to put the whole fleet in flood-safe depots, by depot spacing and intake (simulated). ## The rescue system: when the water rises In Suriname's worst floods, villages along the rivers and districts of the coastal plain were cut off for days or weeks, and help arrived by boat. Celestavia is designed so that the network becomes most useful in exactly those days. - **Energy in reserve.** The fleet's charged batteries hold about **157 MWh**. Half is kept for rescue runs; the other half, about 63 MWh, can feed shelters and clinics through the depots' connectors — roughly a 500 kW hospital for 125 hours. The line's own high-voltage feeder and generation add to it (about 14 MW firm for days and up to 21 MW more for short peaks from storage, if the islanded power kit is built). - **Rescue carriages on battery.** Running on the main or the separate backup motor system, a rescue carriage covers 323–351 km on a large swap pack, over roads that are under water. Ambulance, rescue (basket-lowering), fire and supply cabins (water, food, medicine) ride the same carriages. Battery packs are exchanged by robot at the stations, so a rescue carriage is back out in minutes. - **Inspection in hours, not weeks.** Cameras on every tower, reviewed remotely with automated pre-screening, let about 14 operators inspect the whole network in roughly 12 hours; drones from tower docks take about 6 minutes a kilometre. - **A communications backbone that stays up.** The fibre is carried as a ground wire on the line's own towers, not on distribution poles, and every tower has its own battery backup for **at least 21 days of total power loss**, so its 5G small cells, sensors and cameras keep working through and after the event. - **Water levels, tower by tower.** River, rain and tide sensors along the line give the disaster services a live picture of where the water is rising, and the line moves people out ahead of it. Simulated: battery capacities, ranges, inspection rates and timings are placeholders from the system's design studies; the fibre, 5G and power capabilities are design intentions to be engineered and tested. ## A national sensing and communications backbone Rain, rivers and tides decide Suriname's bad days, yet the gauges that measure them are few and far apart. A Celestavia line puts a tower about every 85 metres — about 6,400 towers across the network — and every tower is a place to carry sensors, power and a fibre connection. #### Fibre optics An optical ground wire runs over every span. It carries the line's own control traffic, high-capacity backhaul for the operators, and fibre to the home and to schools, clinics and farms along the route. The same fibre can work as a continuous sensor: distributed acoustic sensing detects ground movement, pile settlement, impacts and intrusions along its whole length. #### 5G today, 6G-ready Towers host 5G small cells, public Wi-Fi and the line's private radio, fed from the line rather than from the distribution grid, with battery backup at every tower for at least 21 days of total power loss. The fibre and the tower spacing are chosen so that the next generation of mobile networks (6G), and other systems such as satellite ground terminals, LoRa sensor networks and emergency radio, can be added without new structures. #### Early warning for every hazard - Rain gauges and anemometers on the towers, giving a dense real-time rain and wind field during a squall or a downpour - River, canal, water-level and tide sensors at every crossing and along the coast - Lightning detectors, for warnings to outdoor workers, schools and farms - Pile-settlement and ground-movement sensors on the soft clay - Accelerometers and seismometers, joining the regional seismic network - 360° cameras with automated analysis, for floods, fires, blocked roads and incidents - Air quality, heat and humidity The data is shared in real time with the meteorological service, the national disaster-management office, the water and drainage authorities, the university and the utilities. During a downpour, emergency managers would see the rain and the water levels tower by tower and district by district. After it, they would see which areas are flooded or dark and which roads are blocked, within hours. These are design capabilities of the Celestavia platform to be specified with Suriname's agencies, not services operating today. Fibre-optic sensing for ground movement and intrusion is in use worldwide. ## Heavy rain and floods: what Suriname lives with Every proposal for Suriname has to begin with the water. The country has two rainy seasons and about **2,160 mm of rain a year** in Paramaribo, and a single wet spell can bring far more: 200–400 mm fell in one week in May 2006. Most of the population lives on a coastal plain only 0–4 m above sea level, where the drainage canals and sluices depend on the tide: when heavy rain meets a high tide, the water has nowhere to go and the streets flood. Inland, the Suriname, Saramacca, Coppename, Commewijne, Marowijne and Corantijn rivers rise over the riverside villages and the roads to the interior. 2,160 mmrain a year in Paramaribo 87 %of the population on the low coastal plain 78 %of people exposed to river flooding (PDC model) ~10,100people affected by the 2021 nationwide floods ~US$ 41 Mdamage and losses of the May 2006 floods (reported) Recent floods and extreme rain EventWhereWhat happenedPeople affectedRoads and services May 2006 interior floodsUpper Suriname, Tapanahony, Lawa, Marowijne; ~30,000 km², 157 villages200–400 mm in a week; disaster declaredup to 25,000–31,700villages cut off; about US$ 41 M damage and losses (reported) 2021 nationwide floods (Mar–Jun)All 10 districts, incl.

Stations have raised platforms and dry access ramps; the line carries people and supplies across the flooded districts. **River floods**Riverside villages and the roads to the interior are cut for days or weeks; help arrives by boat.Towers on piles are designed against scour at every crossing; long spans cross the flood plains; depots, stations and substations sit above the design flood. **Heavy tropical rain**Visibility drops, roads become slippery, and crashes rise.Guided, automated running is not affected by visibility or road grip; the cabins are sealed and air-conditioned. **Squall lines**Sudden gusts bring down trees, power lines and roofs.Passenger cabins keep running up to 136 km/h gusts; the line is secured above 151 km/h and designed for 242 km/h.

Figures for past events are as reported at the time; gauges in the interior are sparse, so rainfall and flood extents are undercounts. ## The coast, sea-level rise, soft soils and lightning Suriname's coast is young land: marine clay and peat laid down by the mud banks that drift west from the Amazon. It is protected by mangroves where they survive, and it is eroding where they do not. The capital, the main roads, the airport road, the rice polders and most homes are on this plain, which makes sea-level rise a national question, not a coastal one. 0.45–0.78 msea-level rise by 2100 in the scenarios used 0–4 mheight of the coastal plain above sea level up to 24 mdepth of soft clay over firm ground (typical) 23–29 mpile length per tower (simulated) 104–187thunderstorm days a year ConditionWhat happens on the road todayCelestavia's design response **Sea-level rise and spring tides**Low coastal roads and dikes are overtopped at the highest tides; drainage slows and the flooding lasts longer each decade.Stations, depots and substations are raised above the design flood plus a sea-level allowance of 1.0 m. A line on towers needs no embankment that blocks the drainage, and it can be raised at its anchor points if the sea rises faster than planned. **Soft clay soils**Roads settle and crack; heavy embankments sink for years; every road repair is costly.Each tower stands on piles driven through the soft clay to firm sand or clay (23–29 m, simulated), with a small footprint and a light load. Settlement is monitored at every tower by the line's own sensors. **Coastal erosion**Stretches of coast lose tens of metres in a few years where the mangroves are gone.The alignment keeps a set-back from the eroding shore, and the line crosses mangrove areas on long spans with no road cut through them. **Lightning**Strikes cause power outages, damage electronics and endanger people in the open.A ground wire carrying the fibre runs over every span and is bonded to earth at every tower; cabins are closed metal shells; platforms in the open are cleared during close lightning, and the line's detectors warn the public. **Salt air, heat and humidity**Corrosion of exposed steel and electronics.Coastal-grade coatings, sealed bearings, and air-conditioned equipment rooms. **Earthquakes**Suriname's seismic hazard is low.Foundations to the seismic code; line accelerometers join the regional network.

Pile lengths are simulated from typical soil profiles; the Phase 0 geotechnical investigation sets them tower by tower. ## Diagnosis: a country that moves by car, minibus and boat Suriname has 634,431 people (2024 World Bank estimate) and a GDP of about US$ 4.5 billion (2025). About 72 % of them live in Greater Paramaribo and the neighbouring districts of Wanica and Commewijne, and almost everything that moves goes by road. Public transport is mostly privately owned minibuses and buses, about 4,100 of them in 2024, on licensed fixed routes, beside a small state bus company; they run irregularly, and many stop in the evening. There has been no passenger railway for decades. There are about 414 vehicles for every 1,000 people, and the result is daily congestion on the few roads into the capital and across the Suriname River. 634,431people (2024 World Bank estimate) 414vehicles per 1,000 people ~20 minlost in peak traffic into Paramaribo 79road deaths in 2024 112,600crossings on the Corantijn ferry to Guyana in 2024 (people) #### A coast of towns, an interior of rivers The towns string along the coast from Nieuw Nickerie in the west to Albina on the Marowijne in the east, joined by one main east–west road and its bridges. The interior is rainforest, savanna and rivers, where the roads end and the boats and small planes begin. The airport at Zanderij, the gold mines, the hydro reservoir and the river villages are reached by a few long roads that flood and wear out quickly on the soft ground. #### The cost of a road-only country Every household that can afford a car buys one, because the minibus does not run when and where people need it. Fuel, imported cars and spare parts drain foreign exchange; roads on soft clay need constant repair; and the crossings of the Suriname, Commewijne and border rivers are bottlenecks, served by bridges and ferries. Fuel costs about US$ 1.29 a litre for petrol and US$ 1.42 for diesel (November 2026). The city bus fare is held at SRD 14.50 (about US$ 0.38) by a subsidy of about US$ 32 million a year for public and school transport. #### Road safety 79 people died on Suriname's roads in 2024, a rate of about 12.5 per 100,000 people. In 2021, 27 of the 96 people killed were moped and motorbike riders and 19 were pedestrians; most deaths are in Paramaribo and Wanica (28 and 23 of 79 in 2024). Every trip moved from the road to a guided, driverless line is a trip that cannot end in a crash at an intersection. #### Ferries and river crossings Boats still carry people across the Suriname River and to the river villages, and ferries cross the border rivers to Guyana and French Guiana. They are slow, stop in bad weather and at night, and cannot carry the daily commute. A line on towers crosses a river on long spans, without a new bridge. **What is missing is a second layer:** electric, automated and above the traffic and the floods. It would join Paramaribo's neighbourhoods, the airport, the port, the river towns and the rice and mining regions. It would carry the country's fibre and sensors, and it would keep running when the streets are under water. That is the Celestavia network proposed here.

Visitors today reach them by car, minibus or boat, on roads that flood in the rainy season. Tourism brought 261,543 visitors and about US$ 40 million in 2024. 261,543visitors in 2024 US$ 40 Mtourism earnings, 2024 519,171passengers at the international airport, 2025 2UNESCO World Heritage Sites: the inner city of Paramaribo and the Central Suriname Nature Reserve Trips today and with Celestavia (simulated) TripBy road todayCelestavia (simulated)With the faster intercity option (simulated) Paramaribo Centrum → JAP Airport (Zanderij)54 min56 min55 min Paramaribo Centrum → Nieuw Nickerie3 h 354 h 033 h 05 Paramaribo Centrum → Albina (ferry to Saint-Laurent)2 h 102 h 311 h 55 Lelydorp → Paramaribo Centrum26 min26 min30 min Kwatta → Paramaribo Centrum14 min16 min18 min Meerzorg → Paramaribo Centrum14 min10 min11 min Blauwgrond → Anton de Kom University31 min27 min32 min Paramaribo Centrum → Brokopondo1 h 351 h 501 h 23 Paramaribo Centrum → Paranam38 min40 min33 min Paramaribo Centrum → Moengo1 h 381 h 481 h 23 Paramaribo Centrum → Groningen42 min43 min39 min JAP Airport → Paramaribo Centrum54 min56 min55 min Simulated. Celestavia times are cabin rides on the network (lines at about 85 % of line speed: 50 km/h in the city, 70 km/h intercity) plus about 3 minutes of wait and boarding (the simulated average for a rider who walks in; with the reservation app there is no wait at the station). On the timetabled rural stretches, stops on the way add about 2 minutes on average. Road times are the fastest road path at class speeds, with Greater Paramaribo slowed 1.7 times at the peak (estimates). The last column is the optional 100 km/h intercity carriage, an open choice. Against the minibus, which stops on demand and waits to fill, the line gains more. What the network adds to Suriname's tourism #### The historic inner city, without the traffic The World Heritage inner city of Paramaribo is a place to walk, not to park. A station at its edge, with the line kept clear of the protected streetscape and its views, brings visitors and residents in without cars. The heritage review in Phase 0 sets every tower position near the listed area. #### Commewijne's plantations across the river The plantations, the fort at the river mouth and the nature parks of Commewijne are a short hop across the Suriname River. A line on long spans over the river makes them a day trip from any hotel in the capital, and gives the district's residents a fast way to work. #### The ride itself is the attraction Panoramic cabins over the river, the mangrove coast, the rice polders and the forest edge become products that tour operators can sell, with evening runs over the lights of the capital. Toward the interior, the line can open the way to nature parks and river lodges with one tower base about every 85 m instead of a new road through the forest. #### Spreading the benefit Stations in the districts bring visitors to craft markets, farm-to-table food, heritage sites and community tourism in towns that see few of them today. Hotel and restaurant workers get a fast, reliable commute, and a visitor can land at the airport and reach the city or a lodge without a taxi or a rental car. ## The Celestavia Suriname network: 541 km in three phases Our simulation platform drew the network on Suriname's road graph and terrain model. Urban lines follow road centrelines, and river crossings use long spans. It then loaded the network with commuters, school and university trips, airport transfers, visitors and freight, section by section. The result is a **541 km network of 9 lines** with 3 megastations, 248 stations and 6 cargo distribution centres, built in three phases. Figure 1. Proposed network (draft, simulated). The legend shows the three phases and the station types; the dashed orange line is the heavy cargo option tested, which the simulation did not justify.

Simulated with our proprietary platform from census populations, school and job locations, airport and visitor statistics, and placeholder trip rates (all listed in the study). Design year: opening plus ten years. Design-year demand: ~100,000 riders a day and 13,104 boardings in the busiest hour network-wide. Fleet: about 2,222 carriages and 2,702 cabins at opening and about 3,641 carriages and 4,441 cabins at the design year, added as ridership grows (simulated). A second-by-second simulation with each stop's docking windows sized this fleet: pooled cabins carry two to three riders and run back empty over long lines, so it takes about three times the earlier estimate to keep walk-in waits under 10 minutes. ## Peak hours, capacity and how many tracks Each section was loaded with the largest of its peak hours: the morning commute into Paramaribo, the school and university peak, and the airport arrival wave. On top of that came special events and a flood evacuation. One track carries a cabin every few seconds under moving-block signalling (relative braking: each carriage follows the one ahead at its own braking distance plus a margin). That is about **2,500–3,000 riders an hour each way on intercity lines and 3,600–4,500 in Paramaribo**, counting only the share usable with offline station berths.

By capacity alone one track each way carries the design year everywhere, and AP1, E1, PM1, PM2, PM3, PM4, S1 and W1 would need a second track each way only at double demand; on the intercity and airport lines a single track with passing loops would be enough, an option that cuts their cost. Track use peaks at about 33 % of one track at the design year. **Walk-in waits stay under 10 minutes** (simulated, typically a few minutes); **with the reservation app, there is no wait at the station**: the app gives you the nearest available departure. On the long rural stretches (the West line beyond Groningen, the East line beyond Tamanredjo and the South line beyond Paranam) cabins run to a timetable, **a departure every 8 minutes**, and stop on the way only where a rider gets on or off (about 2 minutes on average against a non-stop cabin); riders change to or from the on-demand city cabins at Groningen, Tamanredjo and Paranam, a wait of about 5 minutes on average. The 22 quietest rural stops, with a few riders an hour, are served on call, booked by app or with a button at the stop. #### How many Paramaribo lines We tested 2, 3 and 4 metro lines. Two lines already carry the morning peak (the busiest section at 28 % of one track); the third adds the university and Zorg en Hoop and closes a western loop, the fourth crosses the river to Meerzorg and starts the eastern line. The draft keeps all 4: 339,926 residents within reach. ## Megastations, stations, distribution centres and storage In our other networks a megastation is placed where the simulation finds more than 600 cabin dockings in the peak hour, or at an international airport or gateway. No Surinamese station reaches that number at the design year, so the draft makes three stations megastations: the capital's centre, the three-line hub at Latour and the international airport. Each is a full public building: passenger and cargo terminal, power and fibre node, cold store, automated warehouse, health centre, offices of public services, shops and community space (never casinos or bars). Each also includes a **flood-safe depot and public shelter**.

Those upper floors can be **pre-sold or pre-leased off-plan** before construction, so that buyers and tenants help finance the building, and the station grows with the city around it. #### Regional and local stations Fourteen regular stations serve the district capitals, the border towns, the line interchanges and the distribution centres. 234 small stations serve neighbourhoods, villages, schools, clinics and attractions: 216 two-space stops (one cabin and one cargo or waste box) and 18 four-space stops. They sit beside the line, so through cabins do not slow down, and they are close together where people live: about 2.4 a kilometre in dense Paramaribo and 1.5 a kilometre in the built-up areas, while rural stretches get a stop only at villages, schools, clinics and junctions. At small stations the cabin is lowered to the ground and the carriage moves on; at megastations the carriage leaves with its cabin. #### 6 cargo distribution centres Nieuwe Haven (Paramaribo port), Lelydorp (Wanica / Para distribution and air cargo from the JAP airport line), Paranam (gold-mine supplies), Nieuw Nickerie (rice), Moengo (Merian gold-mine supplies, Marowijne distribution) and Albina (border trade with French Guiana). Goods arrive in containers and leave in Celestavia's 2.5-t boxes to stations, shops, markets and restaurants. #### Storage There are three kinds, all raised above the design flood. Automated warehouses and cold stores sit at the distribution centres and megastations. Depots for the fleet sit every 30 km. Emergency stores of water, food, medicine and charged battery packs are kept in the depots' shelter halls. ## Live near a station, no car needed If you live near a Celestavia station, you do not need a car. A cabin is there when you call it, day or night, rain or flood, and takes you to work, school, the market, the hospital or the airport. As the network grows, more families can choose to live without the cost of owning a car — or a second one — and spend that money on their home, their children and their business. US$ 5,200a year to own and run a car in Suriname (estimate) 586,000residents within reach of a station at the design year (simulated) US$ 23 Ma year kept by about 4,500 households that no longer need a car (design year, simulated) #### Imagine the savings No car loan, no insurance, no fuel, no spare parts, no parking and no repairs after the next flooded street. A family that gives up one car keeps about US$ 5,200 a year (estimate, from local prices of buying, insuring, fuelling and maintaining a car). Their trips cost a cabin fare instead, and their time in the cabin is their own. #### The network keeps growing Phase I serves Greater Paramaribo, from Blauwgrond to Lelydorp and across the river to Meerzorg, and the international airport. Later phases are planned to reach Nieuw Nickerie, Albina, Paranam and Afobaka, and later, across new bridges, Saint-Laurent-du-Maroni in French Guiana and the Guyana border at South Drain. Every new line brings more homes, jobs and schools within reach of a station. Future connections are planned phases, subject to the studies and their financing. Car-ownership costs are estimates from local prices and will be refined; residents within reach of a station are simulated from census data and the draft network. ## Ports, rice, gold-mine supply and freight Almost everything Suriname imports arrives at the Nieuwe Haven in Paramaribo and leaves it by truck, on the same roads the commuters use. Rice from the Nickerie polders travels the length of the coast to the capital or leaves through the western port, and the gold mines and villages of the interior are supplied by long truck runs on roads that suffer in every rainy season. The port handled about 105,950 TEU and 3.1 million tonnes in 2024. 105,950TEU through the Nieuwe Haven, 2024 3.1 Mtcargo through all ports, 2024 167 ktrice a year, mostly from Nickerie 2.0×seaborne exports 2024 against 2021 (oil, gas and gold sectors) Port, terminal or cargo hubRole and volumeCelestavia connection (proposed) Jules Sedney Haven (Nieuwe Haven), ParamariboMain container and general-cargo port on the Suriname River; 105,950 TEU through all ports and 904 ships docked in 2024**Nieuwe Haven** distribution centre beside the port, on the Paramaribo metro (PM1, PM4): containers are unpacked there and their goods leave in 2.5-t boxes ParanamFormer alumina bulk port on the Suriname River; supply route to the gold mines of the interior**Paranam** distribution centre on the south lines (S1, S2) Nieuw NickerieRice and bulk port on the Nickerie River (12 ships docked in 2024); more than 95 % of the rice crop is grown in Nickerie**Nieuw Nickerie** distribution centre at the western end of W1 MoengoFormer bauxite port on the Cottica River (13 ships docked in 2024); on the supply route to the Merian gold mine**Moengo** distribution centre on E1 AlbinaBorder crossing to Saint-Laurent-du-Maroni, French Guiana (33,151 visitors arrived this way in 2024)**Albina** distribution centre and station at the ferry, at the eastern end of E1 Johan Adolf Pengel International Airport (Zanderij)The international airport: 519,171 passengers in 2025, and air cargoMegastation at the terminal (AP1); air cargo to the **Lelydorp** distribution centre South Drain (Corantijn ferry to Guyana)112,600 crossings in 2024Not on the draft network; a later link from Nieuw Nickerie, with the planned Corantijn bridge Which lines carry cargo, and which carry only passengers Every line in this proposal is a **light line**. Light lines carry the 9-seat passenger cabins and Celestavia's standard 10-ft boxes of up to 2.5 tonnes for parcels, fresh food, rice in bags, retail supplies, mine consumables and waste, so the passenger network also does the country's local freight distribution. Heavy cargo lines are separate lines with more ropes, taller towers and carriages rated for full ISO containers of up to 36 tonnes; they cost much more per kilometre. Celestavia's rule is to build them only where container or bulk flows justify the cost, from the ports to inland distribution centres. Our simulation tested each corridor against its forecast container and bulk flows: CorridorLaden containers a year (busiest section)Needed to justify a heavy lineDecision (draft) W1 Kwatta – Groningen – Totness – Wageningen – Nieuw Nickerie5,700~169,000–452,000Light line, cargo in 2.5-t boxes E1 Meerzorg – Tamanredjo – Moengo – Albina8,823~104,000–278,000Light line, cargo in 2.5-t boxes S1 Latour – Houttuin – Paranam10,727~19,000–50,000Light line, cargo in 2.5-t boxes S2 Paranam – Klaaskreek – Brokopondo – Afobaka9,436~58,000–153,000Light line, cargo in 2.5-t boxes The result is a **passenger network that also distributes freight**. Containers are unpacked at the Nieuwe Haven distribution centre and their goods ride 2.5-t light boxes; on the busiest corridor that uses under 2 % of one track. A heavy line becomes worth a new study if a mine or the port commits to whole-box inland haulage of about 30,000 boxes a year or more.

Connections and distribution centres are Celestavia proposals, not discussed with any port operator, rice producer or mining company. ## Power: what the network needs, and where it can come from Our power simulation ran every line second by second through its design day: grades from the terrain model, air-conditioned cabins for hot and humid weather, regenerative braking returning energy to the line, and stations, cold stores and depots. Suriname's national grid, run by EBS, peaked at about 235 MW in 2025. ~39–40 MWnetwork peak (simulated) ~149–165 GWha year, stations and depots included 0.14 kWhper passenger-km, against ~0.40 kWh of fuel by road ~14–17 %added to today's national peak if all drawn from the grid ~14 MWfirm for critical loads in an emergency Traction: 1.5 kV DC, decided for every passenger and light line Celestavia uses 1.5 kV DC traction on every passenger line and every light line carrying 2.5-t boxes: lighter, cheaper carriages with no transformer on board, small substations along the line, and regenerative braking that returns power to the line. **The power source is not decided.** It is an open choice for Suriname and its utility, and each option is costed as a range below. Power-source options compared (simulated ranges; to be defined by further studies) OptionPower-side capital, whole network (US$ million)30-year cost incl. energy (US$ million) National grid (EBS) at each substation, if EBS adds the capacity260–668446–1,231 Own high-voltage spine, fed from the national grid at a few points267–667433–1,239 Hybrid: own spine + grid where it has spare + own generation for the rest267–645433–1,800 Hybrid: own spine + grid off-peak + own storage for the peaks267–678433–1,613 Own spine + own generation only (no grid; diesel, heavy fuel oil, gas or propane)287–645600–1,892 Add-on to any option: islanded kit, storage + own generation for 14 days of reduced service94–190+ capital only (fuel when used) Every option's range overlaps the others (US$ 433 to 1,892 million over 30 years), so none is chosen. Energy is about 29–56 % of each option's 30-year cost, so the price of a kWh matters as much as the hardware. The national grid is short at its evening peak today: in the base case it can spare 0 MW at that hour, yet off-peak it has room for about 77 % of the network's energy (15–100 % across the cases). The rest, about 24 MW at the evening peak (0–39 MW across the cases), needs new grid capacity, own generation or storage charged off-peak (simulated). #### Its own high-voltage spine Most places lack spare grid capacity, and parts of the interior have no grid at all. Like every Celestavia network, the line can carry its own high-voltage feeder along the route, stepped down to 1.5 kV DC at its own substations: US$ 30–81 million (simulated). Where the power comes from is still open: the EBS grid where capacity allows, the line's own spine fed at a few points, its own generation of any kind, and storage. One option studied, an islanded kit of storage in fire-rated containers with its own generation, would let the network run a reduced service for **14 days with the grid down**, for US$ 94–190 million. The power study will set the source. #### Its CO₂ depends on the power source, and we say so The network is 100 % electric, with regenerative braking that returns power to the line. Today about 47 % of Suriname's electricity comes from the Afobaka hydro plant and about 52 % from oil-fired plants (World Bank, 2024); in dry years such as 2024–25 hydro output fell from about 140 to 90 MW and more of the power came from oil. Whether the network cuts CO₂ depends on the power source chosen, which the power study will decide. On today’s oil-heavy grid, where the extra demand would be met by oil-fired plants, it would not reduce CO₂: the carriages alone would emit about 20,000–64,000 tonnes a year depending on the source, and about 46,000–150,000 tonnes with the stations and depots, against about 51,000 tonnes from the road trips they replace (simulated). With a clean supply it would avoid most of those road emissions. #### Batteries: fireproof and swappable Every battery, on carriages, at stations or at towers, sits in a fireproof container with its own fire-suppression system. Carriage battery packs are swappable: a robotic system at the stations exchanges a carriage's pack for a charged one in minutes, and packs of different capacities can be fitted for different trips. The simulation compares swapping with charging in place. #### Towers that keep talking Every tower has its own battery backup for at least 21 days of total power loss, so its 5G, sensors and cameras keep running through a blackout or a flood, whatever the power source of the line. Figure 4. Power-source options: storage and generation needed to run without the national grid (simulated). Simulated. Electricity tariffs, generation and storage prices, and all equipment prices are placeholders listed in the study, with low and high values. No power source has been chosen. ## Estimated investment (profile-level, simulated ranges) The whole 541 km network, built in three phases, comes to **US$ 1.80–2.27 billion with raised depot halls** (most likely about US$ 2.02 billion) or **US$ 1.83–2.30 billion with raised domes** (most likely about US$ 2.05 billion). Both keep the fleet of the three megastation lines in depot floors inside the megastations; the other depots stand on pile platforms above the floods. **The depot type is subject to further study.** Both figures include the fleet, the stations and their access to the line, the power supply, the depots, the towers on piles, signalling, 5G and sensors, the megastation buildings, engineering, land, permits and an allowance for what is not yet designed. Traction power is 1.5 kV DC on every line, as decided; the power source is still open and is part of the range. Each range holds eight in ten of 20,000 simulated draws of the unit prices that are still estimates (steel, rope, piles, concrete, station access, buildings and the rest), each between its own low and high value; prices that move together, such as steel, building costs and the exchange rate, move together in the draws. The allowance for the parts not yet designed is set by how well each part is known: largest for the new parts: the small stops' access to the line and the raised storm depots. Carriages and cabins are priced part by part as series parts (re-checked against public prices in November 2026): a carriage with its cabin comes to about US$ 52,000 (simulated), a little above a small truck (about US$ 43,380 delivered) because of its 1.5 kV equipment and wheel motors. No supplier has quoted yet, so these remain simulated ranges, not prices.

Phase I, with all three megastations on 76 km: about US$ 8.6 million per km including stations, US$ 4.8 million without. P10–P90: eight draws in ten fall inside. Each row is that component's own range, allowance included; the rows do not add up to the total range, because the lowest and the highest prices of different components seldom come together. Figure 7. What moves the simulated capital cost (raised-depot-hall case): the mean total with each unit price held at its own low (P10) or high (P90) value while all the others vary; 20,000 draws, no supplier quotes yet. What would narrow the range most (Figure 7): a firm exchange-rate and escalation basis in the contracts; tower and foundation designs for typical spans with pile tests in the soft clay; a priced concept of the small stops' access to the line (an on-line cabin lift where it is quiet, a short station track with fast switches where it is busy); supplier quotes for the track rope; and a signalling, 5G and sensor concept with a vendor's budget price. #### By phase (all costs, P10–P90) Phase I (76 km, Greater Paramaribo and the airport, all three megastations): US$ 574–749 million. Phase II (389 km): US$ 1.03–1.33 billion. Phase III (76 km): US$ 185–240 million. Engineering, land and the allowances go with the items of each phase. #### Power-source options An islanded kit of storage with its own generation for 14 days of reduced service without the national grid: US$ 94–190 million. A smaller rescue-only kit costs US$ 39–78 million. Both are options, not in the totals above; the power source is still to be decided. #### Heavy cargo, if needed later No corridor's simulated container or bulk flow justifies a heavy line: the busiest, Latour–Paranam (the gold-mine supply route), is at about a third of its threshold. Building the south corridor as a heavy four-rope line (option B) would add about US$ 0.4 billion of hardware at base prices, before engineering and allowances, and adding the eastern line (option C) about US$ 0.9 billion. To be re-tested if a mine or the port commits to whole-box inland haulage. Simulated, in 2026 US dollars, without price escalation, finance during construction or taxes. Building costs use the nearest published Caribbean benchmark (Guyana, 2026 market report) and steel and battery prices 2025–26 market data; the other unit prices are placeholders from Celestavia's cost studies, each with a low and a high value. The fleet is sized for opening-year demand and grows with ridership (about 2,222 carriages at opening, about 3,641 at the design year). Carriages and cabins are added as ridership grows, to about 3,641 carriages and 4,441 cabins at the design year: about US$ 55 million more at the capped prices, in later years. Carriages and cabins are priced at their least expensive designs, from truck- and bus-industry suppliers, as series parts re-checked against public prices in November 2026 (a carriage with its cabin about US$ 52,000, simulated, in the range of a small truck); a cabin or a carriage has no combustion engine, gearbox, steering or axles. No quotes yet. Stations reach the line the least expensive way: 72 quieter ones by an on-line cabin lift, 176 busier ones by a short station track with fast switches (US$ 181–345 million). The flood-safe depots are sized for the opening fleet. The whole-country programme (food, education, health, housing) is costed separately, as ranges to be defined. ## GDP, jobs and the economic case, stated plainly Our impact model follows the network for 30 years. It counts the construction, the operation, productivity and travel time, freight, farm losses avoided, road crashes avoided, flood resilience and tourism, each with low, design and high values. +0.9 %GDP at year 10, design case (0.6–1.9 %) ~1,200–7,400people employed through the ~9 years of construction, direct and indirect (simulated) ~1,600permanent operations jobs (890–2,700), plus indirect #### What the network adds (design case, simulated) - **Construction stimulus** peaking at about US$ 170 million (2.2 % of GDP) in the busiest building year. - **A lasting effect of about 0.16 % of GDP** (0.0–0.87 %) from productivity, logistics, tourism and resilience, after the spending ends. - **Travel time:** about 1.6 million hours a year saved at the design year, worth about US$ 4 million (0.2–5.4 million hours), mostly in Greater Paramaribo at the peak; on the long coastal runs a car is about as fast as a cabin. - **Tourism:** about US$ 3 million a year of extra visitor spending (US$ 0.5–9.6 million) and 56–1,100 tourism jobs. - **Road safety:** about 7 fewer road deaths a year (2–16) of the 79 recorded in 2024. - **Farms:** US$ 0.5–9.0 million a year of post-harvest losses avoided through station cold rooms and refrigerated boxes. - **Floods:** trips, deliveries and working days kept during floods, worth US$ 0.2–2.8 million a year, counted conservatively. #### Stated plainly Counted only as transport (time saved, vehicle and car costs, crashes, freight, floods), the full 541 km network does **not** repay its cost at the design demand. The simulated benefit-cost ratio is **0.25** (0.04–1.03 across the cases) over 30 years at 8 %, on the most likely capital cost with raised depot halls (about US$ 2.02 billion), with carriages and cabins at their least expensive designs, priced as series parts (about US$ 52,000 a pair, simulated). Most of the cost is line, towers on piles and stations along long coastal corridors that carry a few hundred riders an hour; on those runs a 70 km/h cabin is not faster than a car off-peak, and time is valued at Surinamese wages. Road deaths, congestion and tourism, which weigh more elsewhere, are smaller here. Greater Paramaribo and the airport line on their own (Phase I) do better: a simulated ratio of 0.36 (0.06–1.48). The case for Suriname therefore rests on what a road cannot give, the national case: - a flood-proof coastal spine: transport, power and fibre that keep running when the streets and the East–West road are under water; - links to both borders, from Nieuw Nickerie toward Guyana and from Albina to French Guiana; - access to the interior, the dam and the mine supply routes without new roads through the forest; - a country that can grow without every family needing a car; - the whole-country programme around it. It also needs concessional, private or public-private finance and phasing. The capital equals about 45 % of today's GDP (most likely case; 40–51 % across the simulated range), with public debt above 100 % of GDP in 2025, so it cannot be financed on public debt alone; oil revenue from 2028 helps, but phasing comes first. What improves it The model's own levers: building first only where the riders are, Greater Paramaribo and the airport (Phase I alone: 0.36); single track with passing loops on the intercity and airport lines, which carry the design demand on one track (0.25 for the whole network); carriages and cabins assembled by car makers 30 % under our estimate; higher occupancy with demand-responsive dispatch; and the optional 100 km/h intercity carriages. All of them together lift the whole network to about 0.52, and Phase I to about 0.73, with payback around 2048. The power source is not used as a lever. The next study appraises each corridor separately to find the strongest first phase and the right moment for each intercity line. Figure 5. GDP effect by source, design case (simulated). Simulated with low, design and high cases. GDP effects are gross level effects; the benefit-cost ratio is the net measure. Construction jobs follow the method of Celestavia's other country programmes: job-years per US$ million of construction (one job-year = one person working for one year), spread over the construction years. Every assumption and its status (sourced, derived, simulated, estimate or placeholder) is listed in the study. ## Compared with the other systems Every transport system has its place. For a low, wet country of soft clay, wide rivers and heavy rain, though, the questions are particular. Does it keep running when the streets flood? Can it stand on soft ground without sinking?

For comparison: rehabilitating the 138 km Meerzorg–Albina road cost about US$ 1.1 million per km (about US$ 150 million, IDB-financed, without vehicles); light rail averages US$ 25–37 million per km; La Paz's cable-car network cost about US$ 23–29 million per km; an elevated metro or monorail costs US$ 60–200 million per km. #### Where the others still fit Roads remain the backbone for cars and trucks. Buses and minibuses are the cheapest and fastest to start and make good feeders to the stations, and boats remain the way into the deep interior. What none of them combines is what Suriname needs: one system that runs above the floods, stands lightly on soft ground, crosses the rivers, carries passengers and freight, and brings fibre, power and sensors with it. Sources: Inter-American Development Bank (Meerzorg–Albina corridor, projects SU-L1006 and SU-L1021); ITDP via ITF/OECD (BRT, light rail); Transit Costs Project (metro); Mi Teleférico; operators' published wind rules (JR East, Miami-Dade, Hong Kong, New Taipei, London, Paris, Taipei); RWDI (truck rollover). Costs per km are not like-for-like: the Celestavia figure includes vehicles, stations, power and depots, and the road figure does not. ## A whole-country programme around the line As in our programmes for Colombia, Peru, Argentina, Ecuador, the Dominican Republic and Jamaica, the network is the spine of a wider programme. Its principle comes from our mountain community model: *art, science and nature — live, work and play sustainably and regeneratively, and thrive together.* Each item below is a proposal for discussion with the Government of Suriname and its partners, and each will be costed in its own study, as a range. #### Food: the whole chain, from soil to table and back Suriname feeds itself with rice and exports it, yet imports much of the rest of its food and loses part of its harvest between the field and the market. The proposals: - every rural station gets a cold room and a packing shed; - produce, fish and rice ride refrigerated or dry 2.5-t boxes to the markets, shops, restaurants and hotels with no transshipment; - agro-parks beside the stations in the farming districts, from the Nickerie and Saramacca polders to Wanica, Para and Commewijne. Target: replace 10–20 % of food imports within ten years. **Our simulation covers the whole food chain:** the soil, the water, the farming, the harvest, preparation for market, food stores and restaurants, cooking in the restaurants, and finally the leftovers returned for recycling into agriculture, with the aid of Break-Thru Technology, professional chefs and agronomists. It includes growing grain, fruit and emergency foods such as Break-Thru's [Nature's Gold Mix](https://break-thru.ggtrust.com/natures-gold-mix/), a seed-based mix, kept through [Break-Thru Technology](https://break-thru.tech/)'s proprietary long-term storage and food-preservation system. The programme's goal is food that is beyond organic and highly nutrient-dense. #### Beyond-organic agriculture with Break-Thru Technology Soil regeneration on the coastal clays and the savanna sands with [Break-Thru Technology](https://break-thru.tech/)'s ecological agriculture platform: - ecological soil management for soil biology and stronger roots; - seed germination and growth enhancement; - nutrient stabilisation to keep food's nutritional value and extend its shelf life; - AI-guided crop planning over the line's fibre and 5G. Field pilots will be measured against control plots with Suriname's agricultural agencies and the university. #### Education for the AI age A **Celestavia Technical Academy**, with the national training institutions and the university, will train the people who build and run the network: - rope, tower and pile technicians; - electrical and battery-safety specialists; - control-room operators, and drone and camera inspectors. The network needs about 1,600 operations staff and about 4,200 builders at the construction peak. Near the megastations, schools for young entrepreneurs will raise children ready to build businesses in the age of AI, and skilled in the trades that AI cannot replace. #### Integral and preventive health Integral health centres at the megastations will focus on prevention: nutrition, exercise, mental health and community spaces. Telemedicine over the line's fibre will reach every station clinic and the interior's health posts, and rotating specialists will ride the line instead of patients travelling to Paramaribo. Ambulance and supply cabins are part of the national emergency plan. #### Industry: build it in Suriname The network needs about 6,400 towers, about 19,000 t of tower steel, about 410,000 m of piles and 34,000 m³ of pile-cap concrete, and about 1,600 cabins and boxes. Celestavia designs and aggregates; the work is contracted. The proposals: - a tower fabrication and galvanising yard near the port; - pile driving and foundations by Surinamese contractors; - cabin, box and carriage assembly under licence with the car makers, and a rope service centre. Raising the domestic share of the work from about 30 to 45 % keeps about US$ 300 million more of the investment in Suriname (simulated, design case). #### Commerce Megastations host: - markets for farmers, crafts, food and fashion; - co-working and business-service space; - public-service offices and shops for residents and visitors. There are never casinos or bars. Rents and services help fund operations, and minibus owners and drivers on the corridors get the first offer of feeder concessions and station jobs. #### Tourism across the whole country The tourism proposals: - an airport express to Paramaribo; - a heritage station at the edge of the historic inner city, with the line kept clear of the protected streetscape; - day trips to the plantations, the fort and the nature parks of Commewijne; - scenic and evening rides over the river and the mangrove coast; - eco-access toward the nature parks and river lodges of the interior, with edge stations and no line inside protected areas. #### Housing, digital and energy - **Housing:** raised, flood-safe housing within walking distance of the stations, on higher ground and away from the eroding coast. - **Digital:** the line's fibre and 5G nodes offered to the operators and community networks as an open, flood-proof backbone into the districts. - **Energy:** storage along the line, in fire-rated containers, so that the network keeps its sensors, communications and rescue running and can support the national grid in an emergency; the power source is still to be decided. Baselines: General Bureau of Statistics (ABS), World Bank, IMF, the rice-sector study (NOB, 2025) and the 2012 census. All items are proposals; none has been agreed with any agency or partner. Break-Thru Technology's methods will be tested in field trials before any figure is claimed. ## Schedule: Phase I in 36 months Our schedule simulation followed every activity of Phase I through 1,000 runs, each with its own rainy seasons and heavy-rain days: - piles, foundations and towers for 76 km; - ropes and wires; - stations and megastations; - flood-safe depots; - power supply; - signalling; - carriages and cabins built in parallel by existing car manufacturers; - testing; - certification of a first-of-its-kind system. **The result: all of Phase I can be in service within 36 months of the notice to proceed, with resources sized for that target: the simulation gives a more than 99 % chance (about 29 months, P50), and the first sections open from about month 25. The larger opening fleet needed for walk-in waits under 10 minutes makes fleet manufacturing the pace-setter with moderate resources (about 46 months); a second carriage and cabin plant line, or a phased fleet delivery, keeps the plan.** ~25 monthsfirst sections in passenger service (P50, simulated) ~29 monthsall 76 km of Phase I operational (P50, simulated) >99 %chance of all of Phase I within 36 months (simulated) 4 plantscarriage and cabin lines at existing car makers Figure 6. Phase I schedule, months from the notice to proceed: P50 bars with P10–P90 ranges; the red line marks the target month (simulated). #### What the 36 months require - The detailed design of all of Phase I finished before the notice to proceed. - Transformers, substations and track rope ordered early. - Suriname's regulatory basis for the system settled in Phase 0, with an independent safety assessor working from day one. - Carriages and cabins built in parallel by existing car manufacturers, with first units at about month 10. - A construction workforce larger than Suriname's own: 11 piling rigs with pile-cap crews (6 brought in from abroad) for the soft-clay foundations, 6 tower crews, 4 specialist rope crews, one contractor per megastation, about 28 local crews building the 111 small stops of Phase I, 2 rope mills and 2 steel fabricators shipping through the port of Paramaribo. #### Stated plainly The 36 months count from the notice to proceed: contract signed, financing closed, permits and first designs in hand. Before it comes Phase 0 (surveys, geotechnics, environmental and heritage permits, financing and design), which the simulation puts at about 21–24 months. With moderate resources, Phase I takes about 46 months. With a single manufacturer and a long certification it takes about 50. The fastest case simulated, with the system already certified on a prototype line and prefabricated stations, brings all of Phase I to about 26 months (P50); even then the piling on the soft clay and the rope supply set the pace. Certification of a new kind of system is the least certain step. StageWhat happens **Phase 0** (about 21–24 months)Feasibility studies and the first-phase choice; topographic surveys, geotechnics and pile tests on the soft clay, hydrology, rainfall and tide mapping; wind-tunnel tests; environmental review and heritage review for the World Heritage inner city; power-source study with EBS; regulatory basis and safety assessor; financing; detailed design; early orders **Phase I** (36 months from the notice to proceed)The four Greater Paramaribo metro lines (PM1–PM4) and AP1 Lelydorp – Onverwacht – Johan Adolf Pengel Airport (Zanderij): the highest simulated loads and the international airport. **Phase II**W1 Kwatta – Groningen – Totness – Wageningen – Nieuw Nickerie, E1 Meerzorg – Tamanredjo – Moengo – Albina and S1 Latour – Houttuin – Paranam: the coastal East–West corridor to the two borders and the south line to Paranam. **Phase III**S2 Paranam – Klaaskreek – Brokopondo – Afobaka: tourism, the interior and the mine supply routes. Simulated: 1,000 seeded runs per scenario. Productivity rates are estimates, except for sourced benchmarks such as transformer lead times, environmental permit targets and car-plant ramp-up times. Pile productivity on Suriname's soft clay and rope-mill lead times are placeholders until contractors and mills are asked. ## Contact Founder and Trustee Joel Segurola Global Genius Trust USA · Celestavia USA [www.celestavia.com](https://www.celestavia.com) [www.grupogenio.com](https://www.grupogenio.com) [Send a message](https://celestavia.com/en/contact/) ### Do you represent a government, public body or NGO?
