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.
Numbering and livery
The LNER originally painted the Y7s in black with ¼inch vermillion lining; repaints after 1928 omitted this with locomotives in plain black.
Two entered British Railways stock in 1948, becoming BR 68088 and 68089.
Operation and preservation
Dock work was hit hard by the depression, and between 1929 and 1932 the sixteen locomotives which made up the first two batches delivered were withdrawn, nine being sold to industrial use while the remainder were scrapped.
Two have survived to preservation:
- NER No. 1310 (Gateshead, 1891), was withdrawn in 1931 and sold to Robert Frazer & Sons, and sold on to Pelaw Main Collieries Limited in 1933. It passed to the National Coal Board in 1949, who renumbered it 63. In 1965, it was bought by the Steam Power Trust, and has been located at the Middleton Railway since 1965.
- LNER No. 985 (Darlington, 1923), was renumbered 8088 by the LNER in 1946. It passed to British Railways in 1948, who renumbered it as 68088, and transferred it to the Eastern Region departmental fleet. It was sold to the National Coal Board in November 1952 and worked at Bentick and Thurgaton Collieries until 1964 when it was purchased by the Y7 Preservation Society. This locomotive has been located at the North Norfolk Railway since 2004. In December 2010 it was announced that when its overhaul was completed, 68088 would be based at Beamish Museum for three years.
