This polygon occupies part of the area containing the Doncaster Plant Works which constructs and repairs locomotives. Although opened in 1853, this part of the works is first depicted on the 1903 OS map. Famous locomotives made at the plant include the Flying Scotsman and the Mallard. The Mallard holds the world speed record for a steam locomotive. The construction of the works provided a great impetus to the development of the surrounding area leading to the construction of housing a sports ground and church for workers. Prior to the construction of the works, the area was marked on the 1st edition OS map as a nursery. Before this, it may have consisted of strip fields consolidated from furlongs in open fields. Legibility of the former character is invisible.
