Great Western Railway photograph of the facing switch point machine adjacent to the Birmingham South Signal Box with the cast iron control boxes hinged open to expose the internal parts. These point machines were installed by Siemens a few years after the Birmingham North Signal Box system and had incorporated some modifications, but operation was very similar with an electric motor driving a magnetic clutch to operate the point rods and locking bolt. Also visible is the detection bar, parallel to the running rail, which would inhibit operation when a train was on the point switches.
