Colsterdale Light Railway
This ran along up the valley to the site of their reservoir at Roundhill (some 1.75 miles (2.82 km) distant), and connected with the quarries on the high hillside of Colsterdale (on the southern flank).[9] Inward and outward bound traffic was swapped over in a yard to the north of Masham railway station, and from there, the line extended some 6 miles (9.7 km) up the valley.[10][11] Roundhill Reservoir was started and completed first by the Harrogate Corporation, whose aqueduct to carry water south into Nidderdale was also furnished with a 2 ft (610 mm) railway in the tunnel.Leeds initially intended to build one of their reservoirs in a side valley to the north of Roundhill at Spruce Gill Beck,[13] however, the geological conditions were found not to be unstable in that area, so a reformed plan involved building Leighton Reservoir first below the outfall of Roundhill, with a catchwater drain bringing water from Spruce Gill.[14][22] Passenger workings consisted of Paddy Mail trains and occasional specials for the families of the workers on the reservoirs.
