1934 1: 2,500 OS map. Thornton Limestone Works (P W Spencer’s limestone quarry) is about 600yd north of Thornton station. The dates of its opening and closure are not known; Binns (2008) assumes that it was active until the 1920s or ’30s, so it had possibly closed by the time of this map’s publication. A single-track railway into the quarry leaves the Skipton-Colne line at the southern edge of this map extract. There is a network of sidings close to the main line, north of which it passes over a lane. Beyond this bridge is a short loop then a tunnel under the Skipton-Colne road from which the railway emerges into the quarry. Today the abandoned quarry is flooded.
