I made a request for information under the GIPA Act. (NSW equivalent of Freedom of Information). Amongst other things I asked for details of the training given to control centre operators regarding the emergency door release system.

When you pull the emergency door release handle it does not, contrary to what you'd expect, immediately release the doors. Rather, there is a
built in delay, during which time it sends a signal to the control
centre. The operator there can override the door release, so that the
doors will not open, even after the delay time has expired.
Inquiries into past accidents have repeatedly shown that train operators
do not handle real emergencies at all well. My concern is that the Metro centre operators will always respond to a emergency door release signal
by overriding it, and only after that seeking to determine whether there
is an emergency. That is not what they're meant to do, which is to use
the delay time to decide whether to apply the override.
If their immediate response is to override the release, then in a real emergency such as a fire, that extends the time before the passengers
can escape. It isn't even clear that the operators can release the doors themselves once they have applied the override. The passengers may have
to try to operate the emergency release again, and wait for the delay
time to expire again.
The emergency release mechanism has been made very complicated, all in
the name of preventing passengers from operating it and getting out of
the train when they don't need to. There's every chance that in a real emergency with a damaged train, it won't operate in the way it should,
and passengers will die as a result.
NSW seems to be the only place where this approach is taken.
