Does anyone know why the keyboard shortcut to guard's buzzer doesn't work on Class 377 trains? Although it works on Class 313 trains, for example. I can run a three-car Class 313 train in "Driver Only Operation" mode. This is acceptable, especially on Southern, although as far as I know, trains to Seaford have a train guard. However, running a twelve-car train without the help of a train guard seems ridiculous even on Southern rail. So if I want to play the London Commuter add-on, I have to somehow pretend I have a conductor on board, since DTG is unwilling to implement this very distinctive feature for passenger trains. Maybe some MOD, adding a keyboard shortcut to Class 377 for the buzzer?
Not every train will have a key mapped to the guard buzzer. That's just how it was set up. I think only when tsw2 came out, they started binding it to the b key.
