signal and the elevated disc reading from the Down Bay Sidings was a bracket). The box was renamed Oxford Station North when the frame was relocked and renumbered, using 5 bar locking in May 1944. In January 1945 the access to the engine shed was improved. The dog chart and associated locking chart, derived from the dog chart, show the situation in July 1956. The principal changes between May 1953 and July 1956 (i.e. those not shown on the box diagram but included on the locking chart), are the provision of track circuits 12T, 16T and 57T in lieu of F.P.L. bars. This would have affected the locking on signals reading over the F.P.L. in the trailing direction (each way locks removed) and 12 leads 16 (mechanical locking removed and provided electrically). Subsequently 25T was installed in lieu of F.P.L. bar (1957) completing the replacement of F.P.L. bars with track circuits."
