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 The A4 locomotives started to be withdrawn in 1962 with the final members lasting until 1966.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.

The Dapol Black Label Class A4 Capercaillie LNER Garter Blue Valanced 4-6-2 No. 4901 Steam Locomotive is a limited edition model, exclusive to Rails of Sheffield. It is a highly detailed and accurate representation of the iconic A4 class locomotive, featuring a Garter Blue livery.

The model boasts a range of innovative features, including a powerful 5 pole skew wound motor with flywheel, highly detailed body, tender, and cab interior, and loco and tender wheels that pick up electricity. It also features NEM coupling pockets, allowing for easy coupling to other models. The model is all diecast and features a Zimo 21-pin decoder, allowing for DCC sound functionality.

The locomotive's electronic features include working front lamps, dynamic firebox flicker effect, and hi-fidelity sound, recorded from the Bittern locomotive. The model also features user-configurable RealDrive with working brake, and twin speakers in the tender and locomotive. The smoke generator is controlled via the decoder.

The model is highly detailed, with valanced and unvalanced bodies, three tender variations, and single and double chimneys. The A4 class was a high-speed express engine introduced by Nigel Gresley in 1935, and was an instant success, with one of the class, 4468 Mallard, setting the world steam speed record in 1938.

The A4 class was later modified with the removal of the valances to aid maintenance, and some locomotives were fitted with double chimneys. The class was withdrawn between 1962 and 1966, but six examples have been preserved, including Mallard and three others in the UK, one in the USA, and one in Canada.
