#1 - Overall map of the network..
#2 - Detailed map of the southeastern section around Shipley. The electrified network consists of four main parts:
- Lines from Shipley Victoria to Broadstairs via Bury, as well as the Bury-Rochdale and Shipley Victoria-Motherwell via Cresswell lines, electrified 1935
- Suburban line from Shipley Mayfair to Watford, and the Rochdale-Corby line, with transfer station at Radcliffe, electrified 1914
- The 3 Shipley Underground lines, electrified 1906, 1938 and 1947, respectively. The last one shares track with aforementioned SM-Watford electrics between SM and Finsbury, so only the fringes had to be electrified.
While these three parts are self-contained operations, they are connected, so through running under electric power is possible.
The last part is - Shipley Trafalgar to Newcastle and Winchester (electrified 1939), plus a short spur from ST to an aerodrome at Sevenoaks (built 1945, aerodrome currently under construction)
