Trainzmesh file
From TrainzOnline
The Trainzmesh file format is a simple mesh file format created for use with TANE and TRS19. It serves as a simple replacement for the more complex IM file format which was used by Auran Jet in older versions of the Trainz product.
Trainzmesh files have the extension ".trainzmesh" and are created by importing FBX files using Content Manager.
