I haven't actually experienced a passenger run with those big double Decker cars having only them without the end control unit cab. This would mean that the control unit would be a electric engine and it would drive them from the forward point. Seen them around in real life normally 4 of these units joined up in general but can feature longer depending on passenger traffic for the day
Hmm, I don't really understand what you're trying to say. DoSto services without the cab car? That does indeed not exist in TSW, as far as I'm aware of. Neither in reality, apart from som very rare exceptions.
Believe it or not there is a way to uncoulpe a desoto control car from a train,and drive on without it,but you can only uncoulpe if you can find the uncouple option on or near the car you want to uncouple.
