Fascinating report on what could have been a deadly incident at Bank DLR.

An alignment fault on a CCTV camera was noted but, by the split of
responsibilities, the maintainer sent wasn't allowed to re-align the camera.

An intending passenger wedged himself into the door of a train. This caused
the doors to re-open.

None of this was seen by the driver as for unproven reasons he decided not
to follow normal departure procedure but relied on CCTV images alone to
judge departure.

A late-arriving passenger saw the doors opening to release the wedging and
thought that she had plenty of time to board - but quickly found that she
couldn't and backed off (and this is all at the CCTV-invisible door,
remember)

A draw-string on her coat happened to get caught in the door and she was
dragged forward with the departing train.

Fortunately she got one arm out of the coat and the train dragged the coat
off her.

Oh, and the door obstacle detection specification was that the system must
be able to detect a "test block" 30mm thick. Now how many coats,
draw-strings - or human hands - are at least 30mm thick under compression?
