Rail Island

Build your own railway empire on an island

Shape the landscape, lay track and roads, bridge the rivers and tunnel through the hills — then run trains, buses, trams, ships, aircraft and cable cars across the island, and watch them go from a balloon moored above the rooftops. Rail Island is a relaxed transport-building game you can play for free.

Plays right in your browser on desktop and mobile — nothing to install.

How to play

The new-island screen with Hills, Rivers, Woods, Cities and Map size presets to choose from

New island

Choose how the island starts

Set the basic shape of a new map: flatter or hillier terrain, fewer or more rivers, and the island size you want to build on.

Terrain tools

Plan routes through the landscape

Islands are generated with natural-looking coastlines, rivers and broad valleys where your railway can wind through the terrain. When you lay track, the ground can adjust automatically with cuttings and embankments so the line keeps a reasonable grade.

The fleet

Run more than trains

Nearly 350 vehicles, most of them railway and mostly Czech and European: steam, diesel and electric locomotives, multiple units, coaches and freight cars. Beside them run buses and trams on your streets, ferries and liners between your ports, aircraft in and out of your airports, and cable cars over the hills. Preview any vehicle in 3D before you add it.

Bridges

Select a bridge type

Preview each bridge type in 3D, then choose one that fits the height above the terrain. You can build multi-track bridges too, for both straight and curved track.

Rail Island Factory

Missing a model? Build it yourself

Every vehicle and building in Rail Island is generated from code in the Rail Island Factory — an open repository on GitHub. You do not have to be a programmer to add to it: describe the model to Claude Code, let it write the code, and send it back to us.

  • Models made of code

    A locomotive, a bus or a church in the factory is a short program, not a 3D file. That keeps every model light, sharp in the game and easy to change.

  • Described in plain words

    Fork the factory, open it in Claude Code on the web and say what you want — a tram from your city, a station you know. Claude Code writes the model and checks it.

  • Into the game for everyone

    Send your model as a pull request. Once it is reviewed and merged, it ships in a future release of Rail Island, for every player.

PLUS · Every accepted model earns its author three months of Rail Island PLUS — and every model you add to your collection in that time stays yours for good.

Not up for building it yourself? Ask for the model in our Facebook group. Join the Facebook group ↗

For OpenTTD players

Take the vehicles to OpenTTD

Every train, tram, bus, ship and aircraft in the Rail Island Factory can leave as an OpenTTD NewGRF. Pick the models, press Export, and drop the GRF into your newgrf folder.

  • No NML, no sprite drawing

    The factory renders each vehicle from its 3D model in your browser: eight directions, 32bpp, at normal, 2x and 4x zoom.

  • Real figures

    Weight, power and top speed come from the model. Long vehicles become articulated, at true proportions.

  • Over a hundred vehicles

    Czech locomotives and coaches, TGV and ICE sets, trams, articulated buses, ferries and airliners, in all their liveries.
