The London and North Eastern Railway (LNER) Class J39 was a class of medium powered 0-6-0 steam locomotive designed for mixed-traffic work throughout the former LNER system between London and the north of Scotland.

The larger wheels enabled them to be used on both passenger and freight trains, although at the expense of a lower tractive effort.

However the increased speed afforded by the larger wheels caused the big end bearings to overheat, something that was aggravated by their use on passenger trains, and reliability suffered as a result.

64747 served out the remainder of its days as a stationary boiler at the Woodford shed until October 1964.

Graham Farish-Bachmann manufactures the J39 in N scale as BR black with late crest & stepped tender numbered as 64841 and 64880.
