The iconic Mallard is an essential model for any railway fan. Maintaining its world speed record for a steam engine at 126mph, it has long been held as an example of incredible engineering and true style.

The dark blue livery and streamlined shape have reached celebrity status, with the aesthetic appealing as much as the loco’s capabilities.  With an optimised steam circuit, large firebox, and high boiler pressure, the Mallard used less coal and water than previous locos, making it faster and more efficient.
