The Mainline Bus depot is built on the site of the Midland Iron Works. This company was once a major works in the area specialising in wrought iron. It supplied the railway trade amongst others. It was founded in 1844 and continued until the late 1960s. Prior to this the area was probably enclosed as part of the Kimberworth parliamentary enclosure award of 1800. The pre-enclosure map of 1796 shows the area as part of Masbrough Common. Legibility of the former landscape is invisible.
