For DB 146.2 locomotives, the door control does not work. The control icon "T" is still lit even when the train door is open. This icon should flash or go out when the train door is open.
The door controls for the 146 and all German passenger trains are screwy anyway, because IRL they are not centrally opened: the driver unlocks them, but they are only opened individually. Ordinarily the driver uses just the rotating selector switch to unlock/lock, and then the T indicator responds to the doors being opened/closed by passengers.
