I actually know how to do it, too much playing on Railworks, BVE and Microsoft Train Simulator imo. I think I actually wouldn't take as much training to get there as others would. Also, I think it was only me, the train manager and driver on the 09:55 STP to Sheffield service (14/01) that knew about the signal failure outside the Market Harborough area before anything was announced, ground to a halt and I had the thought "that couldn't be a red signal as the other train was about 15-20mins ahead" and I was right.
I think the above also points to playing too much Railworks too
That's gotta be tongue in cheek, right?
