LNER A3-locomotive

Literature tells that the locomotive on the postcard is a LNER A3-locomotive. In the mid 1920'ies the London and North Eastern Railway decided to improve the A1 locomotive, designed by Nigel Gresley and built at the Doncaster "Plant" in 1922  The outcome of the various experiments and modifications made to the A1s in the late 1920s was a new Class A3 "Super Pacific", the first example of which was number 2743 "Felstead". This locomotive appeared in 1928 with increased superheat, long-travel valves, improved lubrication and modified weight distribution. Twenty-seven A3s were built from new, until 1935, with little variation except for a new type of boiler with a "banjo dome", a oval steam collector that was placed on top of the rear boiler ring. The last nine A3 Pacifics were constructed in 1935, and it became a standard fitting on all LNER large, wide-firebox boilers that were applied to new locomotives until 1949. Although all of the original Class A1 locomotives were eventually rebuilt to Class A3 specifications, it was a process that lasted until 1949.
