"Trainz-build" tag

Trainz build is the numbering system allocated to each released version of Trainz. Content may be created for different versions, making use of the newer functions in a more recent release. Consequently, some assets will not function in earlier versions of the simulator.

It is important for assets to list the version of Trainz with which they are compatible. For older Trainz builds, this is done by entering a Trainz-Build number in the model config.txt file. Content Creator Plus will automatically add the correct trainz-build to the config.txt file.

A correctly-constructed asset built for an older version will usually function in a newer version of Trainz, but this is not always guaranteed, as there have been amendments made to subsequent versions. (TBD: List of known breaking changes.) A model using the latest functions will not work in an earlier version. The Download Station identifies which version of Trainz you have installed and when you use the Content Manager, it will not allow the download of a more recent model that is incompatible with your version.
