The GNR Class J9 was a class of two-cylinder steam locomotives of the 0-6-0 wheel arrangement, built in 1896 for the Great Northern Railway .
History The Class J9s were based on the
LNER Class J3s.
[1] The LNER relegated the class to local traffic, and began withdrawing them in 1927. In 1936, the last remaining member of the class, No. 4027, was withdrawn from Ardsley, with no units being preserved.
