In "San Bernardino Line" scenarios, I chose "Race Way". I get into the cab car and set up the train. The reverser lever is in forward position. I start the train moving and it runs backwards instead of forwards. Also, I can't close the doors after getting into the cab car. Bugs?
try using the #3 camera to fly down to the open door and click Close when you get the door prompt. There is a scenario in TSW4 that I did that with, but I don't remember which one it is on the San Bernardino route.
