In 1911 a working agreement was made between Baguley-Cars Ltd (1911) with the Drewry Car Company Ltd. for the manufacture of internal combustion engine railcars. From 1930 a lot of Drewry locomotives were built by English Electric companies. In 1961 the company manufactured railway vehicles, specialising in diesel operated rail traction cars. In 1962 Drewry acquired a controlling interest in what had become E E Baguley Ltd, and formed Baguley-Drewry Ltd in 1987, once again building its own locomotives, in Burton-on-Trent.
