The line was built by the
Manchester and Birmingham Railway Company, which diverted to Crewe in 1841 and merged in 1846 with others to form the
London and North Western Railway Company. This, in turn, became part of the
London Midland and Scottish Railway in 1923. The route from Crewe to Manchester Piccadilly, including the Styal line, was the first section of the West Coast Main Line to be
electrified, in 1959. The line was upgraded in the early 2000s, as part of the West Coast Main Line modernisation programme. A full service resumed on the line in March 2007. The line is joined at Cheadle Hulme by the
West Coast spur from Stoke-on-Trent. At Stockport, it is then joined by the
Mid-Cheshire line from Chester, the
Hope Valley Line from Sheffield, and by the
Buxton line. In April 2006,
Network Rail organised its maintenance and train control operations into '26 Routes'; the Crewe–Manchester line was included in Route 20 (North West Urban). ==Services==
