The London, Midland and Scottish Railway (LMS) was involved in the development of railway electrification of Britain. Like the LNER and the SR the LMS took over several schemes that had been developed by its constituent companies and also completed some of its own. All were suburban lines, in London, Liverpool and Manchester, and were usually steam lines converted to electric traction. Each service is listed below, showing dates of opening and the railway responsible for its conversion.
