Not a day to be proud of for FGW▸ and the Cotswold Line today! True, that two incidents (a bad track bump reported between Kingham and Moreton mid-morning, and a serious failure with the 14:51 GMV-WEY 'West' service at Great Malvern), were largely outside of anyone's control, some of the decisions were however shocking!
Shocking is putting it politely.
I hadn't realised the 17.31 was cancelled. This train would have been well clear of Ascott-under-Wychwood long before either train from Worcester arrived and not that many of the passengers would have been inconvenienced if, as you suggest, it went no further than Moreton-in-Marsh. There are worse places to get stuck for 40 or 45 minutes on a summer evening.
I couldn't quite believe my eyes when I arrived at Oxford to see they had decided to run the 17.00 from Malvern, when the
HST▸ must have bearing down on it fast after finally getting under way. When the Turbo arrived at Oxford, to a packed platform 1 under the canopy, it was carrying more than 200 people off the Cotswold Line. As I was up the far end of platform 2, I could only assume, given how empty platform 1 was after it left and the strain in the engine note as it started, that this Turbo was also grossly overloaded. As we passed the Hereford north of Oxford, I couldn't see how many were on board. Not that many I'd guess, given the numbers on the 166.
I will admit cancelling the turbo at worcester might have caused a problem at Paddington in mid-evening but by that time there are surely Turbos coming spare after the peak. If the crew weren't out of hours, then this Turbo could have taken up the path of the halts return working from Worcester to Oxford.
I would like to think someone, somewhere, might sit down with the train logs and try to work out some better 'what do we do if' scenarios, but in nine years of travelling between Oxford and the Cotswolds, I have to say I see precious little evidence of lessons being learned from these kind of situations, either by Thames Trains or FGW after they took over.
