Hello,

Hopefully somebody here can shed some light on this. Earlier this
evening I was on a northbound Northern Line train, wanting to get off
at
Golders Green as normal. When the train pulled into the platform,
there
was a very brief "beep", but the doors didn't open. After a minute or
so
(the amount of time the doors would normally be open) the recorded
voice
saying the train was leaving came on, and the train pulled away.
There


Is that a situation to push the emergency stop button?
