The London and North Western Railway (LNWR, L&NWR) was a British railway company between 1846 and 1922. It was created by the merger of three companies – the Grand Junction Railway, the London and Birmingham Railway and the Manchester and Birmingham Railway. In the late 19th century the L&NWR was the largest joint stock company in the world.
In 1923 it became a constituent of the London, Midland and Scottish (LMS) railway, and, in 1948, the London Midland Region of British Railways: the LNWR is effectively an ancestor of today's West Coast Main Line.
