Don't know if anyone else has had this problem, but I have some Locomotives that cause Trainz to CRASH when I try to turn them on a Turntable. They are High Nose Diesels with a lot of smoke effects. (I'm at work and can't remember the Type.) Whenever I drive them on the TTable and then try to turn them, the game crashes. I tried these same locos on five or six different TTables and Trainz crashed every time. Just FYI.
