When pressing the door open button on the controller, there are multiple click sounds, same with closing. (Bakerloo)
This has been a longstanding issue with many trains that have sliding doors. During the time that the door takes to close the door control is also animated with the switch/button moving and the sound playing over and over until the doors are closed. It only happens when closing from the controller and not if you use the control in the cab. It’s a strange bug that I don’t understand. It’s very hard to ignore it in the 1972 stock as the button sound is so loud.
There is also the thing where if you try to open the doors with the controller whilst moving, it continues to press the button over and over again till you stop.
