On Monday I went to London Stp on an EMT HST in first class. Given how many folk seem to praise this rolling stock I was surprised how poor the experience was. The coach seemed to transmit every vertical jolt, to the extent that it often felt like we were going down a pot hole (yes I know railways don't have such things....). There was a lot of noise from the vestibule, despite the door to the carriage area being shut. Lastly there were gales of cold air, to the extent my wife remarked as to where the open window might be. I certainly wouldn't like to travel any further than the hour I had on this train. In contrast, the Meridian on the way back was far superior, in spite of me sitting directly above an engine.
