Some time ago, I created a 53' semi-trailer in TSM for "that other simulator", but for whatever reason, never finished it. I have converted it to a 3D Canvas object file, and i'm making it avaiable to anyone who might be interested in it. There is one catch though - it has no textures. With a little TLC (and maybe a few parts additions or replacements) this would make a great static scenery asset for your industries.
The file is free and without restriction, but I would ask that if you modify it, you please upload and share it freely with the rest of the Railworks community.
