I have to agree that you are way out of touch there. Pax forcing their way out of trains, against the instructions of staff, during disruption is unacceptable, as has been widely discussed on here before. However, this is completely different.
For passengers to be dumped inside a closed, locked station with no staff and no means of escape is an appalling mistake for a TOC to make, and it is perfectly understandable that people will force their way out if that is the only way they can escape. Would you really expect people to just sit around for the rest of the night and wait until the next shift turns up?! People who have been delayed for hours on end, people who may be ill, pregnant, elderly or infirm. What if somebody is travelling with a baby or young child, or somebody requires essential medication, or temperatures are freezing? Is it acceptable for them to spend the night on a platform, really?
I think not.
