For the train on topic here, all reports indicate the train did halt
with a least some some cars in the platform, which to me suggests a
controlled emergency stop. Some of the less hysterical reports also
indicate the doors problem was not all cars but only some. One door
open is not good, but get a grip on reality here.


Assuming that the photograph in the ES is of the train concerned,
which it appears to be, the vast majority of the train is in the
platform, contrary to the report from the OP which said that half the
train was in the tunnel.

However, I am a bit mystified why the door interlocking doesn't (a)
just prevent power being taken when a door is open rather than, as the
implication is here, (b) allowing power to be taken then cutting it
off if a door is open. Presumably interlocking of type (b) also covers
the event of a train door coming open while the train is moving,
giving two levels of protection for the price of one.
