I am trying to use the JR MS LT Gray Tunnel that's in Trainz 2012. This tunnel was created by jointed rail and is used on their layout that comes preloaded in the game and looks great on their layout. This being said I know it works for them but I have been totally unable to get it to work. I am reasonably sure it is a problem with my ability to use the content properly and not the content itself. If anyone has some suggestions on how to get this to work I would greatly appreciate it.
