Can you please make the 801 have the same power that it does on the cornish mainline with the great Western express
That's the 800 which actually has full engines. The 801 only has a 1 emergency diesel engine. You aren't going to go fast. I know what you're talking about in wcl where it can run electric power when there's no wires which is a bug btw and shouldn't be happening.
What do you mean? Explain yourself a bit more and if you are saying what I think you're saying I can give you an answer, but currently haven't a clue what you mean.
