Schematic diagram showing Redditch South Signal Box's Signal Diagram and the lever number associated with each signal or point. Bob Essery writes, at an earlier stage there was a ground frame or stage worked connection from the up to the down sidings on the station side of signals 17/18 but was later removed at an unknown date. There was an unusual arrangement which probably dated from the installation of the ground frame whereby Redditch North down starting signal was slotted by Redditch South Signal Box. The term 'slotting' describes an arrangement whereby two signal boxes work one signal and until the second lever is pulled the signal will not clear'. Bob believes that this was achieved at Redditch by the practice of underbolting, a term used to describe the mechanical locking of a lever in a signal box.
