There is one small thing about the Sifa I would like to address: If the Sifa isn't lit (in game), it's not possible to reset it's timer by pressing the switch (IRL you should be able to reset the timer anytime you release the pedal and press again). The same bug occured in the 481 too and it was pretty annoying ever since. 😅
EDIT: And also a feature suggest: Currently I don't see any indicators that the doors can be closed, so I have to open the HUD at every station just to check this. Would it be possible to place an icon on the OBU or give somehow a clue that the passenger exchange has been finished?
