Following on from the success of the A3, and at the insistance of the LNER publicity Department, Nigel Gresley revealed his next class of high speed express engine in 1935. They were introduced, like the A3's, for the long distance, high speed, runs on the ECML to which they settled in very quickly. 

They were an almost instant success, building on the foundations laid by the A1 and A3 classes with the added streamlining both of the outer casing of the engine and a lot of internal components. In 1938 Class A4 4468 'Mallard' set the world steam speed record of 126.4 mph on Stoke Bank south of Grantham while running on a trial service with a dynamometer car (for recording speed etc) and 6 standard coaches. 

During the war years it was found that the valances covering the main running gear was hampering quick maintenance that on other classes would be relatively easy. The decision was taken to remove the valances completely to aid general servicing with the intention of restoring them at the end of hostilities, however this never happened and for the rest of their lives they ran without them. 

The only other major change to the look of the locos came with the fitting of double chimneys, although with the abundant streamlining this was less obvious than on other classes. The A4 locomotives started to be withdrawn in 1962 with the final members lasting until 1966. Luckily 6 have been preserved, including Mallard and 3 others in the UK, 1 in the USA and 1 in Canada.

Prototype information

^* Class names often change over the lifespan of a locomotive, so this is not necessarily the class name used by the operator in the period modelled.

The Dapol Black Label Class A4 Quicksilver Express BR Blue Unvalanced 4-6-2 No.60015 Steam Locomotive is a limited edition model available exclusively from Rails of Sheffield. This model features a DCC sound system and smoke effects.

The model is a highly detailed representation of a Class A4 locomotive, with a 5-pole skew wound motor and flywheel for smooth operation. The model has a diecast body and tender, with NEM coupling pockets and working front lamps. The livery application is exquisite, and the model features a Zimo 21-pin decoder.

The model includes a range of electronic features, including dynamic firebox flicker effects, hi-fidelity sound, and user-configurable RealDrive with a working brake. The model also has twin speakers and a smoke generator controlled via the decoder.

The Class A4 locomotives were introduced in 1935 by Nigel Gresley, following the success of the A3 class. They were designed for high-speed express runs on the East Coast Main Line and were an instant success, with one example, 4468 Mallard, setting the world steam speed record in 1938. The locomotives were modified during World War II to facilitate maintenance, with the removal of the valances covering the main running gear. The only other major change was the fitting of double chimneys. The Class A4 locomotives were withdrawn from service between 1962 and 1966, with six examples preserved, including Mallard and three others in the UK, one in the USA, and one in Canada.
