Which railway locomotive was nicknamed “The Flying Scotsman” after the London–Edinburgh train service?

LNER Class A3 4472 is the locomotive known as Flying Scotsman.

Built at Doncaster Works in 1923 for the London and North Eastern Railway, the locomotive was designed by Nigel Gresley. It was named after the Flying Scotsman passenger service linking London King’s Cross and Edinburgh Waverley.

The locomotive became a celebrated railway symbol and was later preserved by the National Railway Museum. In 1934, it became the first steam locomotive officially recorded at 100 miles per hour, although the record’s circumstances are distinct from later high-speed claims.

Flying Scotsman is often confused with Mallard, another Gresley locomotive. Mallard was an A4, whereas Flying Scotsman was an A3. The locomotive’s number has also changed during its career, including 103 and 60103.
