Geography

Grenofen Bridge over River Walkham

When the South Devon & Tavistock Railway was built by Brunel in the 1850s, several tunnels and bridges were necessary to cover the terrain. The most northerly tunnel of the railway was located in Grenofen.^[2] The tunnel is 374 yards long and today forms part of the Tavistock to Plymouth cycle route, part of the Drake's Trail.^[3][4]

Part of the track forms the Gem Bridge, crossing the River Walkham, just south of Grenofen.^[5]
