Not a good start to the summer timetable, with the 08:49, 09:52 and 10:47 (Melksham times) all cancelled.  Don't know about the 12:07 yet.

"This is due to a member of train crew being unavailable."

Cancellation of 08:49 was quite close to the time it was due /  initial help point advise was to wait for the 10:47 (would her been brilliant thing to do as that's cancelled too!) but people had appointments, connections, tickets for events.   FGW^▸ (First Great Western) / Twitter and Station Manager a great help in getting Taxis - took 8 people from Melksham up to Chippenham.   Don't know about passengers from Westbury and Trowbridge.

Kiss and ride passengers for 09:52 decided to drive to Westbury themselves;  we were a bit overstocked with taxis (that's probably because people saw about the cancellation online, and estimates were based on a guess as to how we might do).   I do note a scathing review on our Facebook page, but it's unclear as to whether that's from an intended traveller or an armchair critic.  Certainly not someone I met at Melksham Station; and (for Melksham where I have been) at least, everyone who's come to the station has made their journey so far.

Very VERY disappointing ... hopefully just "one of those things"; I can personally accept it if the train crew member involved had a significant crisis, on the basis of "these things happen"

I was a little disappointed that the chap who turned up in a First van wasn't able to help ("I'm only here to ....") ... but that's perhaps an operational discussion to have locally.  His was a very different role, but he should have known who to call, I think.
