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. Ivatt had previously designed a modified version of Patrick Stirling's J5 Class of 1873.

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.

The 0-6-0 wheel arrangement was by far the most numerous used by the LNER. 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 …

The North Eastern Railway (NER) Class C1, was a class of 0-6-0 freight locomotives designed by T.W. Worsdell. They were used throughout the NER system, although particularly in Teesside between 1886 and 1962.

A number of different numbering and classification schemes were used for the locomotives owned by the London and North Eastern Railway (LNER) and its constituent companies. This page explains the principal systems that were used.

The LNER 'J' 0-6-0 Locomotives: J71 - J94. Due to the large numbers of different 0-6-0 classes, they have been split into four indexes: The 0-6-0 Tender Locomotive Classes J1 - J20, can be found here. The 0-6-0 Tender Locomotive Classes J21 - J41, can be found here. The 0-6-0 Tank & Diesel Locomotive Classes J45 - J70, can be found here

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 J1. Class Details Ivatt design (GNR class J21) based on his N1 (0-6-2T). Weight: 46 ; Pressure: 175psi; Cyls: 18x26; DW: 5 ft 8; TE: 18,430 lbs.

Saturated engines Nos. 1-15 became LNER J1. Superheated engines Nos. 71-80 became LNER J2

This page is about the construction of a GNR 0-6-0 class J21 (LNER J1) in 4mm/00 from an ACE Products kit. It is intended for the forthcoming layout “Victoria Square” where it will be used for parcels and local passenger traffic.
