I don't know for sure, but I'll give you a quick tip. People really appreciate it when you use the search button up there ^ to see if someone has asked the same question on the forums before.
That's okay. I don't mind. I just thought I'd warn you before someone got "up in arms" about you not using the search. I've seen that all too many times. If you can't find a good answer using search , then you can see if someone answers here. Good luck on your future trainz experience.
