The London and North Eastern Railway (LNER) was one of the major railway companies in the United Kingdom, formed in 1923. It operated in the northeastern region of England and parts of Scotland, providing passenger and freight services. LNER was known for its iconic steam locomotives, including the famous Flying Scotsman, which became a symbol of British rail travel. LNER played a significant role in the development of rail transport, connecting major cities like London, Edinburgh, and York. The company was nationalized in 1948, becoming part of the British Railways system, which unified the rail network across the UK.
