Think so BNM. Because FGW▸ don't...(yes I'm ranting again!) publish revised timetables, I haven't had chance to mess about with OJP▸ to find out Melksham's timetable for today with what services are running. I checked the Melksham LDB earlier and there were two to/from Portsmouth trains, one in each direction, providing an early evening service. Will look at doing it for next weekend's work where the same diversions/closures are in place.
From LDB today:
1715 Melksham - Swindon 1743 (1508 of Portsmouth)
1849 Melksham to Portsmouth 2055 (1817 off Swindon)
1957 Melksham - Cheltenham Spa 2133 (1935 off Westbury)
So, fairly close the the 'normal' timetable for a Sunday, just different origins and destinations.
Oh, and all three ran pretty much to time.
I would have thought that the service would be bustituted from Trowbridge rather than let people travel via Swindon?
Are these alterations in place in two weeks time? That date doesn't yet appear on the FGW website engineering section. Might travel just to experience the TransWilts.
It was only a couple of services that went via Melksham and terminated at Swindon. These were run in place of the normal timetabled services through Melksham.
The majority of the Cardiff - Pompeys were bustituted between Trowbridge and Bath and Bath and Bristol and that is the case next Sunday as well. The following Sunday things are back to normal, at least according to OJPs.
