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. ==Description== 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 H proved so successful, that the NER ordered a further ten in 1891, three in 1897 and five more were ordered by the LNER in 1923. Due to their small size, these engines did not have a bunker in the traditional position behind the cab, so coal was piled up on top of the side tanks immediately in front of the cab. The H shared their simple domeless boiler design with the H1 (J78) and H2 (J79) classes. The locos were originally fitted with dumb buffers, but these were changed for small round buffers during the 1930s, some also gaining vacuum brakes during this period; only hand and steam brakes were fitted when built. Locomotives operating at Tyne Dock were altered to take shunting poles on each corner of the loco, giving the ability to pull a wagon on an adjacent line. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「NER Class H」の詳細全文を読む スポンサード リンク
