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.

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. Thompson designated the remaining members of the A1 class awaiting rebuilding as the A10 Class. Genesis of ...

“Peppercorn”A1型机车能够以95 km/h~110 km/h的速度在平道上牵引这样的旅客列车。 受到BR于20世纪50年代制订的现代化和内燃化计划影响，到1966年夏天，所有49台“Peppercorn”A1型机车均已退役。 最后一台退役的机车是“Saint Mungo”A1-60145号机车，它的运行时间仅有17年。

The first two engines appeared from Doncaster works as GNR locomotives 1470 and 1471 (later 4470 and 4471 and then BR 60113 and 60102) and they were originally classified as A1 engines. They were a logical development from the GNR Atlantics, but nevertheless caused a sensation and great interest when they arrived.

No. 1470, Great Northern, was rebuilt as the solitary Thompson A1/1, the rest as LNER Class A3. BR No. 69523; Serviceable. BR No. 60103 Flying Scotsman; Undergoing refit. Construction started by the GNR, but delivered to the LNER. ^ "Doncaster-built locomotive returns home". National Railway Museum. Science Museum Group. 25 January 2021.

The London and North Eastern Railway LNER 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.

Gresley became one of Britain's most famous locomotive designers with his famous line of Pacifics. These started with the GNR A1 (which continued to be built by the LNER, and then upgraded to A3), and peaked with the famous A4 streamlined engines. Of the distinctive A4 s, Mallard still holds the world speed record for a steam locomotive.
