"The train at platform (x) terminates here, all change please, all change"
From a similar era on the SR:
"Please stand clear of the train at Platform 4, this train is not for public use".
Common at Guildford in the 80s for terminating trains.
Sometimes when the same message was done manually:
"Please stand
WELL AWAY from the train on Platform 4, this train is not in service".
(as if something dire would happen if you even got close to the terminating train!)
Then there was the Woking sequence for the half hourly dividing/attaching Basingstoke and Alton services:
"Woking. This is Woking. Please stand clear of this train and keep all doors closed. This train is about to make a detachment|an attachment. Please stand clear, stand clear, until the detachment|attachment is made".
(Train divides)
"The front 4 coaches are for Basingstoke. Calling at Brookwood, Farnborough, Fleet, Winchfield, Hook and Basingstoke. The rear 4 coaches are for Alton. Calling at Brookwood, Ash Vale, Aldershot, Farnham, Bentley and Alton".
Presumably other stations which had regular attachment/detachment had very similar announcements.
Does the strident "Stand clear of the platform edge, fast train approaching. Stand away there! Stand away!" or similar still prevail?
Oddly I don't remember such an announcement at Woking in the mid-80s, even though the hourly Weymouth would pass through non-stop at great speed in both directions.
Seemed to become more popular in the late 80s and 90s.
