In 1923, the LNER inherited four pacifics, to two classes each consisting of two locomotives, one class from either of two of its constituents, the Great Northern Railway (GNR) and the North Eastern Railway (NER). The Great Northern Pacifics, were of GNR Class A1, designed by Nigel Gresley and numbered 1470/1.

Below are the names and numbers of the steam locomotives that comprised the LNER Gresley Classes A1 and A3, that ran on the Great Northern (GNR) and latterly the London and North Eastern Railway network. They represented Nigel Gresley's attempt to standardise steam design.

Great Northern is historically significant because it was the first Pacific to be built by the Great Northern Railway (GNR) as a prototype of the new '1470 class'. It was also the only original A1 to not be rebuilt by the LNER as an A3.

Now for Gordon's true origins - the fictional side of the A0 Pacific locomotive story. We believe he is in fact the A0 design, albeit rebuilt and modified to a mechanically identical, but outwardly unique, locomotive. The description of Gordon in TIOS is clear:

It would be in these two crucial areas that the A0 Pacific, if built, would have seen major modifications. The rebuilding of some of the Raven Pacifics, with a Gresley Taper Boiler (and Gresley standard pattern cab), shows how the original A0 …

Sep 3, 2021 · A proposed 4-6-2 Pacific design which is a modification of the GNR C1 Atlantic which was designed by Henry Ivatt. The A0 to put it simply is the C1 but with another set of drivers to turn it into a 4-6-2. The A0 predates Gresley's A1 Pacifics, so the A0 was used as a testbed of this type of design.

Gordon is a GNR/LNER Gresley A0, the prototype of his class. The only other A0 is Thompson (the Flying Thistle). Both were used experimentally to find faults in the design.

Sep 18, 2023 · Gordon is the senior member of the engine family. He is the fastest and most powerful of Sir Topham Hatt's string - and he knows it. His combination of speed and strength means he has pulled the Express more than any other engine on Sodor.
