Mergers
During the 1920s, the improved performance of motor transport gave significant competition to the trams from the many early omnibus companies. Not to be left out, in 1920 Balfour Beatty established the Midland General Omnibus Company (it was initially called the General, but changed its name after buying the Midland Bus Company from Kimberley). The M.G.O. shared the Notts & Derbys base at Langley Mill.
The three Balfour Beatty companies, the Midland General Omnibus Company, the Notts and Derbys Tramways Company and the older Mansfield District Traction Company, formed a single group of companies called the Midland General Group. The Midland General snapped up many of the smaller companies in the area in the 1920s and 1930s, taking over Brewin and Hudson of Heanor, Williamson & Son of Heanor, J.T.Boam of Ilkeston, and the Heanor & District Omnibus Company.
