The steam locomotive Flying Scotsman was built in 1923.
Constructed at Doncaster Works for the Great Northern Railway, the locomotive entered service on 24 February 1923. It was designed by Nigel Gresley as an A1 Class 4-6-2 “Pacific” locomotive, although it was later rebuilt and classified as an A3.
The engine initially carried number 1472. In February 1924, it was named Flying Scotsman after the prestigious express service linking London King’s Cross with Edinburgh Waverley and renumbered 4472. Later numbering included 60103 under British Railways.
The year 1923 can be confused with 1924, when the locomotive received its famous name, or 1928, when it hauled the first scheduled nonstop Flying Scotsman service. It also became famous in 1934 as the first steam locomotive to reach an officially authenticated 100 mph.
