I was at Kings Cross this afternoon, and a 'not in service' 73TS pulled in. It was announced "this train has been taken out of service because of defective safety equipment".
In car 3, one of the double doors was partially open, and the orange light was lit up on that car. There was a member of staff in the carriage presumably guarding anybody from coming through the half open door at stations where it was on the platform side.
I was trying to imagine the system for closing the doors, and couldn't understand how one door of the double set could be shut but the other half open... I concluded somebody could have jammed something in the mechanism? But the doors must be quite versatile to survive many years of rush hours.
Also I didn't think the motors would work if the orange light was on? Or at least I imagined that that the train would operate at a reduced speed if it was possible to override it. But the train accelerated out the platform (I think normally) with the door half open... (thankfully for me, otherwise I would never have got home!)
