The error occurs when using the GP38-2 engine on the N542-A Service. When the end of the train passes the first signal, while the train is moving forward, the SPAD occurs, and ends the session. There is no signal passed in the direction of travel, so the SPAD does not make sense. This has occurred to me 3 times so far with the error always occurring at the same location. Let me know if you need pictures, as I have it documented from 3 tries of the same situation. Thank you!
