== Summary ==
The signal diagram at Bridgnorth signal box, 17 October 2015. The black ovals are the track circuit indicators, which light red in the presence of a train (or if a track circuit fails). The pilot light in the top right corner would indicate that the diagram is receiving power if no track circuits are lit - except that on this day, the pilot lamp had failed!
The small label placed over the diagram at the right hand edge of Platform 1 is a modification to the distance to signals 4/18 - the signal had been moved 5 yards further from the box a few weeks previously.
