The London and North Eastern Railway (LNER) Class A8 was a type of 4-6-2T steam locomotive, designed by both Vincent Raven and Nigel Gresley.

After a series of trials throughout the North East Area, all of the remaining H1s were rebuilt as A8 4-6-2Ts between 1933 and 1936.

Allocations of the 45 locomotives were split between the North East / Newcastle area, the Yorkshire Coast Whitby and Scarborough, Hull, and Leeds (Neville Hill).

Diesel railcars were rapidly introduced during the 1950s, and the A8s quickly became surplus to requirements.
