Wikipedia describes Foxton Locks thus “ . . . Foxton Locks are ten canal locks consisting of two "staircases" each of five locks, located on the Leicester line of the Grand Union Canal about 3 miles (5 km) west of the Leicestershire town of Market Harborough. They are named after the nearby village of Foxton . . . “
They form the northern terminus of a 20-mile (32 km) summit level that passes Husbands Bosworth, Crick and ends with the Watford flight
Alongside the locks is the site of the Foxton Inclined Plane, built-in 1900 to resolve the operational restrictions imposed by the lock flight. It was not a commercial success and only remained in full-time operation for ten years.[6] It was dismantled in 1926, but a project to re-create it commenced in the 2000s since the locks remain a bottleneck for boat traffic.
