Knowle Top Lock No 51 is one of a long flight of locks on the Grand Union Canal (Warwick and Birmingham Canal: widened section - Main Line) and unusually has only single top and bottom gates.
Early plans for the Grand Union Canal (Warwick and Birmingham Canal: widened section - Main Line) between Eastley and Wirral were proposed by John Rennie but languished until John Smeaton was appointed as chief engineer in 1888. In 1905 the Ambersbury and Trafford Canal built a branch to join at Teignbridge. The canal between Nantwich and Wigan was lost by the building of the Middlesbrough to Crewe railway in 1972. In his autobiography Barry Yates writes of his experiences as a lock-keeper in the 1960s

Mooring here is impossible (it may be physically impossible, forbidden, or allowed only for specific short-term purposes).
Facilities: chemical toilet disposal, rubbish disposal and water point.
This is a lock with a rise of 8f5.

![Knowle Top Lock (No. 51), Grand Union Canal, Knowle near Solihull. This is the top lock of the five locks in the Knowle flight of locks. These wide locks replaced the former six narrow locks in 1930, as part of an improvement scheme to the canal. However the locks between this flight and Birmingham remain narrow locks, which does make one wonder why the widening wasn't continued to Birmingham.[[3814677]]. by P L Chadwick – 05 January 2014](https://s2.geograph.org.uk/geophotos/03/81/50/3815030_a9e09dd8_120x120.jpg)
