Flying Scotsman is an LNER Pacific steam locomotive completed at Doncaster in 1923, but its name is also easily confused with the long-running London–Edinburgh passenger service called The Flying Scotsman.
The locomotive was built as an A1 Pacific and later rebuilt to A3 specification.
It received the name Flying Scotsman and number 4472 in connection with LNER publicity and became one of the company’s best-known locomotives.
In 1928 it hauled the first scheduled non-stop London to Edinburgh working of The Flying Scotsman service using a corridor tender that allowed crew changes while the train was moving.
In 1934 the locomotive was officially recorded at 100 mph on a test run, a major British steam-speed milestone.
The locomotive continued through later LNER and British Railways service under different numbers, liveries, and mechanical configurations.
After withdrawal from regular service it passed through private preservation ownership and traveled internationally, including tours outside Britain.
The National Railway Museum later acquired Flying Scotsman for the national collection following financial and public fundraising efforts.
The museum has emphasized that relatively little of the locomotive is physically untouched from 1923 because normal service and repeated overhauls replaced many components.
For TransitSatellite, “original Flying Scotsman” should therefore mean continuity of identity and history, not an untouched set of 1923 parts. Any visual should specify era, number, livery, and A1 versus A3 configuration.
