By 1900 some 40,000 people were employed, producing 40 new engines a year. Electric power and lighting was installed in the Locomotive Works during 1910, supplied by the company's new generating plant located across the Derby canal at the rear of the Works. An earlier and smaller scale electric generating station had been built by the Midland during March 1893 in Calvert Street, Derby to provide current to light the station offices, the Midland Hotel and the Locomotive Works offices. A textile research facility was opened in Calvert Street for upholstery and seat materials. This facility is thought to have used the buildings made redundant by the closure of the 1893 generating station when the new generating station was brought on line in 1910.
