History of rail transport in Great Britain 1948–1994

The history of rail transport in Great Britain 1948–1994 covers the period when the British railway system was nationalised under the name of 'British Railways', latterly known as British Rail until its eventual privatisation in 1994.

The railway system in this period underwent modernisation, reorganisation and rebranding, some of which proved controversial. The use of steam locomotives on the network also ended in this period. Due to falling passenger numbers, rail subsidies from the government were necessary to keep the railways financially viable. Concerns about the levels of these contributed to the Beeching cuts that closed down many less well used lines.
