Category:File formats

The follow articles describe the format of various user-editable files used within the Trainz environment.

When creating files for use with Trainz, care should be taken to follow the specified format accurately. Even if a particular deviation from the documented format is permitted by the current game and tools, it may become disallowed in future versions as loaders are updated and validation techniques are improved.

If you develop software which reads these file formats, you should accept and ignore minor deviations where feasible, in order to future-proof your software. Base your file reader on the documented format, not the particulars of the current Trainz implementation. It is likely that implementation-specific details will change between Trainz versions, whereas the file formats are typically extended but not often replaced.
