Simutrans

Simutrans is the open-source transport simulation that has been growing since 1997. Start with a bus line between two villages and end with freight trains, cargo ships and an airport: haul coal, mail and passengers between towns, industries and landmarks, and watch the map change as your lines connect them. The included pak64 art set carries over a century of vehicles, from horse carts to maglev trains. Choose a map, pick a start year between 1880 and 2050, and build at your own pace; a full tutorial and four scenarios teach the economics, and your company can go bankrupt if it stays in the red for three months. Save and load freely; the whole economy runs offline on your device.
