Out of interest, is it theoretically possible that a train could be given the wrong route where there is no way for the driver to know until it's too late to stop in time? I'm thinking like, a set of points where, by the time the driver sees a signal showing which way the points are set, it would be impossible to stop the train before the points?
Trowse Junction Up Main, is quite close, you get a green on Norwich side of the bridge, but you cannot see CO552 until you clear the bridge, even then if you brake fairly sharp you can stop, but it is not unknown for a train to pass CO552 by coach length or two
there was one there many moons ago, Signaller long retired, A Peterborough train was wrong routed Up Main at Trowse. took the route, did not stop, or at the next signal (CO546), was stopped by putting a signal back to red at Swainsthorpe, Driver came on the SPT, had not realised he had gone the wrong way !
Issue then was... he did not sign the route ahead, or back towards Norwich !
Had to source an 'Anglia' Driver, who took train forward to Stowmarket, then Ely where there was a new Driver to take to Peterboro.
