HST failed to stop at Saundersfoot

[Harrythecat]

I was on the summer Saturday GWR HST service from Pembroke Dock to Paddington yesterday. As we approached Saundersfoot at about 10.45. the train manager announced that passengers leaving the train must use the rear 4 carriages but the train did not stop at all despite 20 people being on the platform waiting for the train.
Does anyone know why this happened other than the driver forgot to stop and in which case what would be the consequences for him if he did forget. The train manager clearly thought we were stopping

Could be a number of issues; a diagram discrepency, an issue which meant the Driver was unable to safely bring the train to a stand (poor rail conditions, technical problem causing concern that the train might have difficulty starting again), late running meaning stops were omitted, and so on. The TM should usually be aware of most of the above though, with the exception of poor rail conditions meaning the train unexpectedly failing to slow satisfactorily.

'Fail to calls' do happen from time to time, it's generally good old fashioned human error. How that would be dealt with would depend on various factors including the root cause and any history of other incidents, and so on.
