Stations are indicated by an '#' symbol prior to the place name. Signal boxes are indicated by numbers in the left hand column. Location names are as shown in the 1960 Sectional Appendix and may be different from the station name.
These signal boxes were virtually opposite each other and governed the connections between the Lancashire and Yorkshire Railway, the Oldham, Ashton & Guide Bridge Railway and the London & North Western Railway at Oldham. So far, I have so far found it impossible to establish when these connections were made.
