So we all know the door system on TSW 2: You press a button in the drivers cab and every passenger door on the train opens. On the London Underground that is realistic - but on most other routes, especially German ones, the system is different: The driver merely unlocks the doors by pressing the button, they do not open automatically. Only if a passenger pushes the button on the door itself it will open. And the door will close a few moments after nobody has passed through it automatically, instead of the driver closing every door at the same time. I do understand that this feature would not make much sense in the game now as there are so few passengers. Not many doors would open at all. But I really think it would be awesome to have in the upcoming Rush Hour pack. It would just add so much more realism to the game!
