Nigel Gresley's A1 Pacific class emerged in the twilight years of the Great Northern Railway, a result of an idea that Gresley had nurtured since 1915. The First World War put his plans for new express passenger locomotives on hold but he applied his new three cylinder, conjugated valve gear designs to the O2 and K3 freight locomotives before returning to his plans for an express passenger Pacific in 1920, producing his 4-6-2 A1 design.
No.1470 'Great Northern' was the first to enter service on the 11 April 1922 and Gresley confidently claimed that his A1 class could pull 600 ton trains which in September 1922 no.1471 'Sir Frederick Banbury' did. Compared to the similar LNER design by Vincent Raven, Gresley's A1 consumed less coal and water and was considered the better design, consequently the LNER chose the A1 design over the LNER A2.
This Hornby model of 'Hermit' has a five pole skew wound motor and a diecast running plate which adds increased weight for improved traction. Also worthy of note is the addition of a flickering firebox which illuminates the fully detailed cab.
