The North Eastern Railway (NER) Class H, classified as Class Y7 by the London and North Eastern Railway (LNER) is a class of 0-4-0T steam locomotives designed for shunting.

Introduced in 1888 by Thomas W. Worsdell, six were built in 1888. Their simple, bare design easily navigated the tight curves and poor quality track which they ran on. The Y7 proved so successful, that the NER ordered a further ten in 1891, three in 1897 and five by the LNER in 1923.

Due to their small size, these engines did not have a bunker as such. Hence, coal was often piled up on top of the side tanks. The Y7s shared their simple domeless boiler design with the J78 and J79 classes.
