Goods Junction
A shot taken through the cab of a diesel multiple unit of the Goods Junction signal box on the Llangollen Railway.
Just beyond the signal box the two tracks merge into a single line. The signalman is holding the 'token' in his right hand that will be handed to the driver to give right of way on the single-track section. The signals for travel in the opposite direction cannot be set until the token is in its place in the signal box at the other end of the section.
This system may seem foolproof, but it isn't idiot-proof as was proved near Abermule station in 1921. The idiots in question were a station lad who failed to swap tokens and a driver who failed to look at the token to see if it was for the correct stretch of track.
