It is situated at the north end of Calstock Viaduct which carries the railway at high level over the River Tamar.

[1] The 3 ft 6 in (1,067 mm) gauge East Cornwall Mineral Railway was opened to Kelly Quay at Calstock on 8 May 1872.

Wagons with goods from the mines around Gunnislake and Callington were brought down the hillside on a 0.4 miles (0.6 km) cable-worked incline with a gradient of 1 in 6 (17%).

This line was a branch from Bere Alston to Callington Road and crossed the River Tamar on Calstock Viaduct.

A short section of the narrow gauge line was retained to serve a lime kiln, but the wagon lift and all the sidings were taken out of use in September 1934.
