The Cheshire Lines Committee (CLC) was formed in the 1860s and became the second-largest joint railway in Great Britain. The committee, which was often styled the Cheshire Lines Railway, operated 143 miles (230 km) of track in the then counties of Lancashire and Cheshire. The railway did not become part of the Big Four during the implementation of the 1923 grouping, surviving independently with its own management until the railways were nationalised at the beginning of 1948. The railway served Liverpool, Manchester, Stockport, Warrington, Widnes, Northwich, Winsford, Knutsford, Chester and Southport with connections to many other railways.

A joint railway is a railway operating under the control of more than one railway company: those companies very often supplying the traction over the railway.
