Can’t complete the scenario because the Headlights don’t show as off (even they are) before you remove the Master Key which is necessary before changing ends of the train.
Agree. Even with a joystick driver, the lights show off in the sim yet the action won't complete. Hint: There is a mod that will let you complete it here: https://www.trainsimcommunity.com/mods/c3-train-sim-world/c75-utilities/i2703-tsw-god-mode-alpha-025
I had a hell of a struggle with this on PC. In the end I kept toggling the headlight switch and I think the objective cleared on “dim”. However it’s a rather silly way to end the scenario as you then walk to the other cab, sit in the seat and it just ends.
