GER Classes S46, D56 and H88
The GER Classes S46, D56 and H88 (classified Classes D14, D15, and D16 by the London and North Eastern Railway) were three classes of similar 4-4-0 steam locomotive designed by James Holden (S46 and D56) and A. J. Hill (H88) for the Great Eastern Railway. 
They were given the nickname "Claud Hamilton" after the pioneer engine of the class, named after Lord Claud Hamilton (1843–1925) the chairman of the Great Eastern Railway
Railway by Beyer Peacock, and it is one of these locomotives that is preserved today.
These locomotives were built to succeed the three classes of 4-4-0 employed by the GER on express services which were becoming heavier as the railways prospered. Classes S46, D56 and H88 (LNER D14, D15, and D16) were collectively nicknamed "Claud Hamiltons" because the first S46 (built at Straford in 1900, numbered 1900) was named after the then-current chairman of the GER, Lord Claud Hamilton
