Hornby R30349 Dublo BR, A4 Class, 4-6-2, 60016 'Silver King' - Era 4
Overview:
The LNER Gresley A4 is one of the most iconic express locomotives in Great Britain. Its streamlined casing was a classic symbol of the attitude towards speed and design in the 1930s when the railways saw increased competition from road and air travel. The LNER Board knew that they had to make travel between the major cities faster, more comfortable and more reliable.
Nigel Gresley, the LNER's Chief Mechanical Officer, travelled on the Fliegende Hamburger diesel locomotive in Germany and was impressed by its streamlining, although he realized it was only efficient at high speeds. Gresley was certain that a modified A3 Pacific, with streamlining, could haul greater loads than other locomotives at the same speed or faster and a series of trials were conducted to confirm the A3's suitability.
With trials successfully completed, the LNER Board gave Gresley the go-ahead to create the "Silver Jubilee" streamlined trains, the first of the new streamlined A4s. The streamlining of the A4s' steam circuit, higher boiler pressure and extension of the firebox to create a combustion chamber made them more efficient than the A3 as they consumed less coal and water- especially later on when they were also fitted with a Kylchap double chimney. This improved their free steaming capabilities further.
