The LB&SCR H2 class was a class of 4-4-2 steam locomotives for express passenger work. They were designed when D. E. Marsh was officially Locomotive Superintendent and were built at Brighton Works in 1911 and 1912. They were an immediate success and shared with the H1 class the London to Brighton express trains including the heavily loaded Pullman services the Brighton Limited, and the Southern Belle.

One member of the class was withdrawn in 1949, but the remainder continued in regular use until 1956. No. 32424 "Beachy Head" was the last survivor, it was withdrawn in April 1958, and none were preserved.

No examples of the H2 class were preserved, but on 29 October 2000 the Bluebell Railway announced its intention to reconstruct a replica of SR/BR period Beachy Head. Many surviving locomotive parts had been assembled including an ex-GNR 'Atlantic' boiler, and an ex-LB&SCR B4 class tender chassis. The boiler was tested around August 2018.
