There were no interlocks or correct side enabling on the old victoria line stock, this was why drivers had to walk across the cab to the platform side to open the doors at stations
At Uxbridge sidings there was a siding which had not been used for a long time, myself and one other driver had to run a train in and out of it in order to clear the rails, it took for trips,8 journeys before the signals picked up and sis before they were considered reliable.
