I was at Sheffield this evening (Sat) expecting to catch the 1900 London service. I arrived off the train from Liverpool on Pl.8 and spotted an 810 on Pl.2 loaded up, engines running and ready to go but it wasn't the 1900, it was the 1800 'Delayed' It was 810011 and eventually left at 1930, not stopping at Derby or Long Eaton (diverted down the Erewash due to a points failure at Ambergate) It was chaos at Sheffield, nobody seemed to know what was happening and even when the signal turned to green it was five minutes before the train got away.
810011 seemed to running ok but I saw two very large guys, dressed in black with Hitachi lanyards and insignia walking through the train and back again, I imagine this is quite a common occurrence at the present time?
