I saw and photographed 150926 a little earlier, see....
https://www.ontheupfast.com/p/21936chg/29343358204/x150926-12-42-gloucester-frome-warminster on its way into Frome at Berkely. Having had a fairly lengthy layover at Frome station it is just about ready to leave with the 14.59 service to Warminster via a reversal at Westbury. An interesting journey of some eleven rail miles that by road is a far more direct seven. The arrival and then subsequent departure from Warminster of this train will coincide with the commuting school children from the large Kingdown school near to the station that has many pupils attending from a wide part of West Wiltshire; I should know, I used to work there!
