The Chippenham and Calne Line was a five mile long Great Western Railway built single track branch railway line that ran along the valley of the River Marden in Wiltshire, England, that ran from Chippenham railway station on the Great Western Main Line to Calne via two intermediate stations, Stanley Bridge Halt, and Black Dog Halt. Built as a replacement for the overwhelmed Melksham Calne and Chippenham Branch of the Wiltshire and Berkshire Canal, the line was authorised on 15 May 1860 and opened to freight 29 October 1863.
