Some more info as regards this former line. Opened in 1871, it was originally steam-driven and ran for a distance of four miles from Bottoms Dept. (now used by United Utilities) to Woodhead Reservoir dam wall.
It was used for carrying both men and materials, in particular clay for use in patching up the original Woodhead Reservoir dam wall, which construction work had been started in 1848 but not completed until 1877.
In 1904, the steam-locomotive was replaced by electric traction, the power for same being supplied by a hydro-electric installation using water discharged from Bottoms Reservoir. The electric railway ran between Bottoms Dept. and Crowden; the electric power being fed by an overhead trolley line.
In 1938, the hydro-electric installation was abandoned, and mains electricity was used instead, in conjunction with a transformer and rectifier.
In 1947, the length of the line was reduced from four miles to two-and-a-half miles, being the section between Bottoms Dept. and Torside reservoir dam wall.
In 1950, the overhead trolley power line was removed, and the electric locomotive scrapped.
Between 1950 and closure in 1968, a Ruston Hornby diesel loco was utilised, until the railway was finally abandoned, and the track ripped up, after almost 97 years of use.
