In 1915 the railways of Britain consisted of 20,000 miles of track owned
by 120 companies. The country could not support so many diverse and, in
some cases, duplicitous operations and it was decided that they would
have to be brought together into a neat bundle of just four companies to
cover England, Scotland, Wales, and part of Northern Ireland. The
Railways Act 1921, known as 'The Grouping Act', became law on 1 January
1923. After this, 120 separate railways were combined to make just four
large companies, to control our railway network, including an airline,
shipping and road haulage companies, hotels, rolling stock and
infrastructure. They were known as The Big Four: The LMS (London Midland
and Scottish Railway); the LNER (London and North-Eastern Railway); the
SR (Southern Railway) and the GWR (Great Western Railway). This book
commemorates This new photographic book commemorates the Big Four across
their heyday, 100 years after their introduction.
