It would be nice to see a GWR reskin of the 377 we have in game to use of the GWE route, whilst the route we have in game is set in 2015, electrification still exists up to the Heathrow branch and I would assume that the electric 377 will still work on the diesel tracks as track types are not programmed in like in TS20, with the 3rd rail being more of a cosmetic than a necessity.
