we have conductor mode so it would make sense to have conductors while you're driving too especially on routes like the LIRR MBTA and amtrak routes where they use conductors it would make a lot of sense to have them
You do realise the game runs poorly as it is now and you want to add something you would see for like 5 seconds at most
I certainly think on routes where the Guard/Conductor (or in the case of slam door stock, station staff or even passengers themselves) operate the doors, it should not be part of the driver’s duties to operate the doors. And part of the atmosphere of despatching a train from a station is the whistle blowing and often exchange of hand signals between platform staff and the Guard. Sadly lacking in our rather sterile TSW stations.
