A guess but it is virtually impossible to stop people alighting from the
WAGN trains to head to the Tube regardless of how many announcements are
made [1].


Probably because the announcements are often complete crap !

I've lost count of the number of times I've heard the familiar...

"Trains on such and such a line are seriously delayed we advice you
to use other routes".

Only to make my way to the platform anyway, find a half empty train
arrives within minutes, and I get to work on time.

People only take notice of announcements if they have a good track
record of accuracy.
