Transport Fever can be modified and extended by mods. Mods overwrite, add, or manipulate existing resource files. These resource files are kept in a folder named
There are many different types of resources:

A commonly used tool is the free open source software Blender. To find out more about Blender visit https://www.blender.org/.

There are other resource files of various types, including but not limited to:
These resources can be modified and extended in two ways:
Changing files directly in the installation folder is possible, but NOT the recommended way of modifying Transport Fever!
Instead, a mod should be created. From a file system perspective, a mod is simply a directory containing all the necessary data and script files. The directory name serves as the mod's unique identifier and contains a version number. See Directory structure for details.
In Transport Fever, mods are not enabled globally, but on a per-game basis: Every save game remembers which mods are active. This has the advantage that multiple games with different sets of active mods can be played without hassle.
Content loaded outside of the actual game (e.g. main menu backgrounds) can’t be modded.
Please refer to the reference page for more information about scripting and examples of the most common resource types.
