OpenTTD

OpenTTD is a business simulation game in which you earn money by transporting passengers and cargo by road, rail, water and air. You build a transport network linking cities and industries, move goods through production chains and expand your services as the world develops. It is an open-source remake and expansion of the 1995 game Transport Tycoon Deluxe.

Build your network

Create roads, railways, docks and airports on procedurally generated maps of up to 4096 × 4096 tiles. Routes can pass through dense city streets, across oceans and rivers, and over high mountains. You can play in one of four climates.

Transport passengers and cargo

Work alone or with friends to complete production chains and deliver finished goods to towns. Assemble a fleet of hundreds of vehicles and transfer cargo across an interconnected network that can combine different modes of transport. Cargo destinations can be optional.

Expand and adapt

As the years pass, technological improvements bring new modes of transport, towns grow, and industries appear, change their production or fail. Expand stations and add network capacity to meet demand and avoid delays.

Customize the game

Community-made mods are available through an in-game content service. They include real-world vehicles, new industry sets, custom scenarios and more.
