The A4 Mallard

The A4 Mallard boasted an iconic steamlined design, enhancing its aerodynamics, but contributing to visibility problems for drivers.

East Coast Main Line

Built to run express passenger services on the East Coast Main Line, the LNER Class A4 Steam Locomotive remained in service until 1966 when the advent of diesels saw their demise.


In all, six of the locomotives have been preserved, two examples are currently overseas.
