Cajon Pass Causing Ctd

I have CAjon Pass and just recent it has been causing the game to crash. I have tried everything I'm on PC. can anyone help me.

 

Works fine for me. Tried a Steam file verification?

 

As mentioned above do a verification of the game files, it sounds as if the files for the route might be corrupt. If you do not know how right click on Train Simulator, then choose Properties and select Installed Files. Then select verify game files.
