Can anyone tell me what, in terms of rolling stock, the service to Weymouth that departs Bristol Temple Meads at 1749 on weekdays is currently diagrammed as?

I am particularly interested to know if it is formed of 2 units, one of which is taken off at Westbury with the other one continuing to Weymouth. If so, what service does the unit taken off at Westbury then go on to form?

Real time trains shows an 18:41 departure from the same platform at Westbury that that 18:40 to Weymouth left from - empty to the DMU sidings.

It show an arrival at 19:18 from the DMU sidings to form (judging by the platform) none other than the 19:32 to Cheltenham Spa via Swindon.  There is, however, an earlier train to the DMU sidings at 18:10 - carriages dropped off a Cardiff to Portsmouth service, so they *might* be the ones to form the 19:32.   There is also (a little later) a movement to the carriage sidings of the 19:39 arrival from Great Malvern.

I'm noting that I've got used to seeing a set swap of the TransWilts unit between the 18:21 arrival and the 18:32 departure - with the crew beetling down the subway from platform 2 to take over the train at platform 3.  However, the timetable I chose above (new timetable from December) shows the same train in use, so perhaps diagrams are changing?

None of this relates to observation on the ground at around that time - sad, really, as I think I may have been the one who arrived at 18:21 then hung back to 19:32 on one of the count days - however, I was busy watching the set swap then I switched off as it had been a long day.   I do recall something dividing - getting all the Weymouth folks forward.

The 1856 terminator from Bristol Parkway tended to form the 1932 to Cheltenham Spa via Swindon when I was last observing in earnest, and I suspect that may well still be the case.

There is a unit taken off at Westbury, and after shunting to the sidings it forms part of the 20:38 back to BRI.  At least, that's what happened tonight!

Other parts of the train are the 19:39 arrival from GMV and 18:21 arrival from SWI.

Both Frome and Warminster extension options look impractical due to other trains ...


So it hangs around for 2 hours ...

Very useful to see that the Shunt Movements at Westbury are being shown from December Timetable.    Almost everything terminating has to get out of the way rather than stay in the Platform due to the volume of trains.
