As I have previously mentioned: SWT▸ tell you "coaches 1,2 & 3 will go here......4, 5 & 6 will go there", having stuck labels all down the train saying "A, B, C............." etc !
No longer
AFAICT▸ , since they binned reservations in December...

Actually - in the 3 years (or so) that I have been using the Temple Meads to Waterloo service (always on Advance tickets) I have never been given a seat reservation, only a general one for the train. That didn't stop them continuing to label the coaches though - BUT, I did note today that the Waterloo train was "letterless". To be honest, I hadn't noticed on the last couple of trips !
I think that might have been because reservations were only offered on the Waterloo - Exeter main route. Last years summer timetable only shows the reservation diamond on the first up train, but only in the Exeter column, not the Bristol column, IYSWIM. But I imagine the whole train could have been given letters on its previous departure from Waterloo anyway, and they'd just stay in the door windows until they were next altered...
