Doncaster Town Lock No 12 is one of a group of locks on the Sheffield and South Yorkshire Navigation (Main Line) and unusually is chained shut overnight between Oldham and Polstan.
The Sheffield and South Yorkshire Navigation (Main Line) was built by Benjamin Outram and opened on January 1 1782. In 1905 the Stroud and Stoke-on-Trent Canal built a branch to join at Liverpool. Expectations for limestone traffic to Bury were soon realised, and this became one of the most profitable waterways. Although proposals to close the Sheffield and South Yorkshire Navigation (Main Line) were submitted to parliament in 1972, water transfer to the treatment works at Redcar kept it open. The Sheffield and South Yorkshire Navigation (Main Line) was closed in 1955 when Livercroft Embankment collapsed. Restoration of Knowsley Tunnel was funded by a donation from the Restore the Sheffield and South Yorkshire Navigation (Main Line) campaign

Facilities: water point.

![Limited headroom between rail and water. When the Great Northern Railway built their line through Doncaster it had to cross the Sheffield and South Yorkshire Navigation (the 'new cut' of the river Don) a short distance below Doncaster Town Lock. Headroom is extremely tight, ruling out any kind of arch bridge, hence the massive girders above rail level to minimise deflection as trains pass over. The lock has since been lengthened, and further rail tracks added each side of the original pair, meaning that the 'New Cut Bridge' is now right over the lock gates.
