So yesterday evening I was on a train into Blackfriars (won't give the time so as not to get anyone in trouble) on which (at least half of[1]) the doors failed to release, however the staff thought they had (based on an announcement the driver made before disappearing), and the driver seemed to have disappeared. So a number of egresses got pulled as a result.
How might this have happened? Can an SDO failure lead to the driver thinking the doors were released when they were not?
(As an aside I question the sense in the passcom being behind glass on 700s - this would have been a good time to use it but having to break the glass is a real dissuader)
[1] I got to a door which had had the egress pulled before getting to one that had been correctly released, this was about half way down the train.
