Welcome to the OpenTTD Wiki

A user-edited manual and development guide for users and developers of the open source transport simulation game OpenTTD, based on the gameplay of Transport Tycoon Deluxe.


The manual provides in-depth information on how to play. If you are new to the game, our Tutorial will show you how to set up your first transport route and continue expanding your network from there.

If you've played the original 1994 edition of Transport Tycoon Deluxe, you may like to read the comparison of OpenTTD and Transport Tycoon Deluxe to see what's changed.

Finally, for any general questions check the FAQ.


This section covers all aspects of non-graphics OpenTTD development. For those new to development, the FAQ should answer any questions you have. You can then move on to current development or helping out with translation if you wish.


Reference and links for NewGRF graphics development, both 8bpp and 32bpp.

The OpenTTD Community

If you want to learn more, help out writing documentation or get further gameplay help then check out the following:

Helping with the Documentation

The OpenTTD documentation is stored and edited using this wiki. Feel free to start editing as soon as you feel you can, but read the Manual of Style first, and make any tests in the Sandbox.

Visit the village pump to discuss any major changes or additions to the documentation, or you can start right in on requests posted in the article requests. Also:

  • Some articles need smaller changes to satisfy our needs, and there is a list of these. If you don't feel up to writing full articles then this may be a better place to start.
  • There are also some articles that require more work before they can be called finished, and you can browse them in Expand category.
  • Finally, there are rarely articles concerning current events which will become outdated - why not check the information in these is still current if you have a spare moment?
Getting Help

Do you need further help that the manual can't provide? Then try our forums, the main source for help and developer's information, or join our IRC channel.
