Plans were discussed for a 387 crowd buster from Cardiff for rugby and other events. Guess it didn't happen due to COVID but the signage is up on Cardiff station and the wires are live all the way.
It’s a shame that GWR, in their wisdom, removed the HSTs from the safety case up into Paddington. 4 coaches is better than nothing, and would have at least allowed some kind of service this morning, even if it meant connecting into 387s. Some drivers still sign both HST and 80x so I’m sure it could be feasible.
