London and North Western Railway

The London and North Western Railway (LNWR) was a British railway company between 1846 and 1922. In the late 19th century the LNWR was the largest joint stock company in the world. The LNWR was formed in 1846 by a merger of the Grand Junction Railway, the London &amp; Birmingham Railway and the Manchester &amp; Birmingham Railway. The London terminus was at Euston railway station
In 1923, the LNWR became a part of the London, Midland and Scottish Railway (LMS) under the Railways Act 1921. In 1948, it became the London Midland Region of British Railways. The LNWR may be seen as an ancestor of today's West Coast Main Line.
