One of the most famous of all steam locomotives, ‘Mallard’ still holds the world speed record for steam. In July 1938, it reached 126mph on Stoke Bank.

Entering service in March of that year in LNER Garter blue, it had full side valances and red wheels, as depicted by our highly detailed model. It was renumbered 22 in 1946, by which time it carried wartime plain black. When it was withdrawn from King’s Cross in April 1963, it was in lined BR green and numbered 60022.

The locomotive is preserved in its original livery at the National Railway Museum in York. 'Mallard' has always been one of our most popular models. In 2026, we have given the A4 a tooling update and the model now includes the new Hornby steam generator technology, working headlights and tender lights.
