On the Northern Line, At 0640 at Finchley, the rear of an engineering train travelling north on the southbound road became de-coupled and travelled all the way down to Warren Street. It was only stopped by the gradient of the track.
There was a train in passenger service ahead at Tottenham Court Road, which was told to drive and keep driving until it got to Kennington.
It could have been a very serious catastrophe. TfL's statement that noone was at risk is ridiculously callous.
Thanks once again to Tube Lines. They are really earning TfL's £300 million buy-out. Will we see a proper enquiry or another whitewash?
And London Underground can think again about getting rid of all those 'superfluous' station staff. Who would have evacuated the platforms with their proposed early-turn staffing levels? The service was a nightmare throughout the day and staff needed to be there.
