LNER Class A3 4472 Flying Scotsman

No. 4472 Flying Scotsman is a 4-6-2 Pacific steam locomotive built in 1923 at Doncaster Works for the London and North Eastern Railway to a design by Sir Nigel Gresley. It worked long-distance express trains on the East Coast Main Line, notably the Flying Scotsman service between London King's Cross and Edinburgh Waverley, from which it took its name. It was built as a Class A1 and rebuilt to Class A3 form in 1947. On 30 November 1934 it became the first steam locomotive officially authenticated at 100 miles per hour (161 kilometres per hour). After retirement from regular service in 1963 with about 2.08 million miles behind it, it passed through several private owners, toured North America from 1969 to 1972 and Australia in 1988 and 1989, and set a record there for the longest non-stop steam run at 422 miles. The National Railway Museum acquired it in 2004 and a restoration finished in 2016.
