The Pudsey Loop was a railway line in West Yorkshire, England, which served the town of Pudsey and offered a second connection between Bramley and Stanningley in the east and Laisterdyke and Dudley Hill in the west, in addition to the existing line between Leeds and Bradford.
The line branched off the Leeds–Bradford Exchange line west of Bramley. Shortly after, a track from Stanningley joined the line in a trailing junction, effectively forming a triangular junction. Just after passing under Lowtown street, the first intermediate station in Pudsey Lowtown was reached. Crossing under Robin Lane, Radcliffe Lane, South Parade, and New Street, the line reached second intermediate station and former terminus Pudsey Greenside. The two stations were located at either end of Pudsey town.
West of Pudsey Greenside station the line passed under Carlisle Road and through Greenside Tunnel, continued through a short cutting, passed under Smalewell Quarry track, then over Tyersal Beck on an almost straight embankment which was reported to be the largest of its kind in Europe, over Tyersal Lane, and under a farm track near Tyersal House. It joined the line from Ardswell and Gildersome to Laisterdyke at Cutlers Junction under the bridge of Arkwright Street, from where the tracks continued west to Laisterdyke on the Leeds–Bradford Exchange line and east to Shipley and Windhill on the Shipley and Windhill Line. Furthermore, a track connection existed south of Cutlers Junction between Tyersal Junction and Broad Lane Junction, forming another triangular junction.
