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.

Given the GER classification of D56, the LNER would class the Belpaire Clauds as D15. The last four D15s were built with superheaters. Two were built with 18 element Schmidt superheaters, and two were built with 72 element Swindon superheaters and matching GWR (Great Western Railway) jumper-top blastpipes.

D15 class covered those built as D15 engines and the D14 locomotives rebuilt with Belpaire boilers. Many of these were later rebuilt as D16/2 and D16/3 locomotives. D16/1 was the classification given to the original D16 engines which had shorter smokeboxes.

2021年5月18日 · Beginning in December 1903, the GER put a Belpaire-boilered variant of the Claud Hamilton that had more boiler tubes and a slightly larger grate. The firebox didn't quite match the boiler heating surface increase, but the class merited series production nonetheless.

2023年6月19日 · The Great Eastern Railway S46, D56 and H88 4-4-0 classes were built between 1900 and 1939 and worked mainly on East Anglian lines. The S46 and D56 (LNER D14 and D15) classes were given the nickname "Claud Hamilton" after the first engine of the class.

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.

The first GER S46 4-4-0 No 1900 Claud Hamilton at an unknown location. Peter Kerslake says "The first of its class, 1900 was built in March 1900 and was the forerunner of a total of 121 locomotives built over 23 years. It has the ornate G.E.R

The engine – and those that followed – carried hand-painted cast GER crests on their driving wheel splashers. The locomotive was subsequently awarded the Gold Medal at the Paris Exposition. Meanwhile, a further ten engines numbered 1890-1900 were completed, and they proved to be a most successful express passenger design.
