The HST▸ off 2020 Paddington to Great Malvern is supposed to stay in the sidings at Hereford, but cannot at the moment because the shore supply (external electrical supply to keep the engines warm etc) doesn't work and is so old that Network Rail are having problems finding obsolete spares. This HST is having to run empty to Bristol TM‡.
bugger! I left that one there yesterday and last Friday and one day the week before that.
