I am using the 3DTS Tehachapi II Template with the latest version of Activity Generator.
An AI Grain Train pulled by 2 SD75s and a Dash 9 repeatedly passes the siding red signals and either blocks the main or crashes into the moving player train. This occurred at the lower end of Walong siding and the north end of Marcel.
Any thoughts on this situation--never seen anything like this in any other MSTS activity (over 4 years).
