The GNR Ivatt Class 1 0-6-0 (LNER Class J1) was a class of fifteen inside-cylinder 0-6-0s designed for express goods work. They were Henry Ivatt's first original class of 0-6-0.

The Ivatt J1 (GNR Class J21) 0-6-0 Locomotives In 1908, Ivatt introduced these 0-6-0 locomotives to operate the fast goods trains that the Great Northern Railway (GNR) was introduced at that time. Following his own standardisation policy, Ivatt based the J1 design on that of the existing N1 0-6-2T locomotives, and used the same boiler, motion ...

These engines are, in respect to their boilers, cylinders, motion and wheels, practically interchangeable with the 0-6-2 suburban tank locomotives of the “190” class, and were intended to work express goods and mixed traffic on the main line. They are illustrated in Fig. 115. Following are the leading dimensions:

Class J21 / J5 (Locobase 8923) Data from Richard Marsden's LNER Encyclopedia ([], accessed 25 November 2007). Henry Ivatt's last saturated-boiler design was this set of mixed-traffic locomotives that had their production run curtailed by the adoption of the J22 with a superheated boiler (see Locobase 8924). Two did have superheaters installed ...

It was used mainly for locomotives intended for freight, branch, and shunting work. If any single type epitomises the British steam locomotive from the mid-19th Century, it is the inside-cylinder 0-6-0 tender loco.

T W Worsdell had recently designed the successful J15 goods locomotive for the Great Eastern Railway, and his new design for the NER, the Class C (LNER J21), had a number of external similarities. They were more powerful than the J15s, and they were fitted with large comfortable cabs that were noted for their convenience.

LNER J5 (GNR J22) Ivatt built these twenty medium-powered goods locomotives in 1909-10, to meet the increasing goods and coal traffic being experienced by the Great Northern Railway (GNR) at that time. They had the same dimensions as the existing mixed traffic GNR Class J21 (LNER J1) locomotives, except they had smaller 5ft 2in coupled wheels.
