The High Marnham Test Track is a linear railway test track created in 2009 and centred on Lodge Lane, Tuxford, in Nottinghamshire in the United Kingdom. It houses Network Rail's Rail Innovation & Development Centre (RIDC), originally known as the Rail Vehicle Development Centre (RVDC). The main route is approximately 14 miles (23 km) long and rated for speeds up to 75 miles per hour (120 km/h). It is primarily formed of a 10+1⁄2-mile (17 km) former section of the Lancashire, Derbyshire and East Coast Railway running between Thoresby Colliery Junction at the western end, and High Marnham Power Station at the eastern end. Additionally a 4-mile (6 km) branchline diverges northwards over the Bevercotes Colliery Branch via Boughton Brake Tunnel to Bevercotes.
