A harbour line from Elsbridge to Knapford was opened in 1885 and used horse-pulled wagons. Later after the Tidmouth, Wellsworth and Suddery Railway and the Sodor and Mainland Railway were joined into the North Western Railway the horses were replaced by steam engines. In 1915 a bay platform was opened at Knapford and was connected via a Branch. After 1947, Thomas was sent to run the line.
The lead mines at Toryreck closed in 1930, but opportunities of stone traffic from Ffarquhar opened and the line to Elsbridge was extended. In 1956, the improvement scheme of the harbour at Knapford was started, the branch to the harbour was rebuilt on an easier gradient and the stations were moved north of the river. The harbour line is now used for goods.
