I've seen notices that imply this, perhaps the train knows when it's
physically in a station and is automatic until it leaves.


Perhaps that is the case as some models of trains have a pretty fast pick up
and perhaps the driver won't be able to react quickly enough to an alarm if
part of the train is still in the station.

I'm sure that it's quite easy for a train to tell if it is still in the
platform.
