Waiting at Manchester Piccadilly is an electric multiple unit bound
for Hadfield and Glossop. To cope with and contribute to post-war industrial recovery, in 1954 a new bore was created under the Pennines alongside the then extant Woodhead Tunnel on the Great Central Railway’s route to London from Manchester. In addition, the line was electrified at 1500volts DC to pioneer modern traction for trains, in particular coal, across the backbone of industrial England. At the same time, EMUs of the same specification as those then recently introduced for London Liverpool Street to Shenfield services, were built for the suburban lines heading east from the then Manchester London Road. These evolved under TOPS to be Classes 306 and 506, the difference being that once the Shenfield line became equipped for 25Kv AC electrification, these Manchester 506 sets became the only overhead DC current collection passenger trains in the UK until their demise in 1981.
