The London and North Eastern Railway Gresley Classes A1 and A3 locomotives represented two distinct stages in the history of the British 4-6-2 "Pacific" steam locomotives designed by Nigel Gresley.

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.

The first two A1 Pacifics were built in the twilight years of the Great Northern Railway (GNR) and entered service in 1922. The A3 was a modification of the original A1 design, and all of the surviving A1s were eventually rebuilt as A3s.

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.

Realising the need for standardization, Gresley adopted his GNR Pacific design as the standard express passenger locomotive for the LNER main line, designating it 'A1' within the LNER locomotive classification system.

While no GNR built locos of this class were preserved, 60163 Tornado was started in 1994 by the A1 Steam locomotive trust, and is running on the main line. https://www.a1steam.com/
