Doors on trains seem to have gone through various cycles of user control - first being fully under the control of the user, then being locked in by the guard, then being back under user control in the days of the slam door stock. A conversation on Twitter about door controls made me wonder, what is the current 'method' that doors are under for control?
I.e., when a train pulls into a station, how are the doors controlled? Does the driver/guard simply control locking, or do they actually open them, or CAN they open them in some instances, and in others let the passenger do it via the door opener buttons? Do the door opener buttons do anything at all, or are they there simply to give us the illusion of control?
The only one I could say I know about is the Chiltern Bubble car, as that has interlocks the guard controls, but otherwise you have to turn a nob to open them. Sliding doors are a little more intriguing I think.
I've never really paid enough attention to work out one way or the other, so I wonder if anybody has a more definitive answer?
