mesh

This the name of the mesh that is being used within the asset. There maybe more than one mesh.

Trainz uses and can understand two mesh extensions either ".im" or ".trainzmesh". The second one is the current file extension to the mesh. It is created by trainz when an asset is imported into trainz.

if you have the ".lm" extension on the mesh name this point to a text file (LOD file). The mesh tag could also refer to the mesh itself i.e.. industry.im. If this were the case the asset would not have LOD mesh reduction.
