The London and North Eastern Railway Class J38 was a class of steam locomotive designed for freight transport. They were designed by Nigel Gresley and introduced in 1926. A total of 35 were built at the LNER's Darlington Works in 1926 and they were used in Scotland.

The Gresley J38 0-6-0 Locomotives. The J38 0-6-0 locomotives were the first LNER group standard type, but only one batch of thirty five were built due to the advent of the more versatile J39 0-6-0 modification.

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.

Ex-LNER Class J38 0-6-0 No. 65910 awaits departure from the branch terminus at Leslie on 16th August, 1961, with the lightly-loaded 4.10pm goods for Markinch, shunting as required at Auchmuty Paper Mill and Haig's whisky bottling plant.

Although the J38 was the first LNER Group Standard design and was also an 0-6-0 goods locomotive, only one small batch of 35 locomotives were built. The J39 appeared later in 1926, and was essentially a J38 with larger wheels.

The NBR F Class (LNER Class J88) was a class of 0-6-0 tank locomotives, designed by William P. Reid on the North British Railway. [1] They were used for dockyard shunting duties. [1]

This was designed at Darlington for Class J39, which had larger wheels than Class J38. Thus the boiler was based on Diagram 97A, but with a 2½in shallower firebox to clear the larger wheels. These boilers could be fitted to a J38 but not vice-versa. The J39 was a universal 0-6-0 type intended to supersede almost all pre-Grouping 0-6-0s.

Ex-LNER Gresley 'J38' class 0-6-0 No. 65918. Built at Darlington in March 1926 as LNER No. 1421 and withdrawn in November 1966. Sir Nigel's 0-6-0 class 'J38' was somewhat overshadowed by his achievements with his Pacifics and V2s.

The class was introduced by Nigel Gresley in July 1926, based on his previous Class J38 (introduced in January 1926) but with larger driving wheels. The larger wheels enabled them to be used on both passenger and freight trains, although at the expense of a lower tractive effort.
