The C1 Class, as it was known under both GNR & LNER classifications, was designed by Henry Ivatt as an enlarged version of what became the LNER C2 Class. The principle of the design was to produce a powerful, free-steaming engine to haul the …

In Dec, 1902, appeared the first of a class of passenger express engine, which is to the modern Great Northern locomotive equipment what Mr. Stirling’s famous 8-ft. singles were to the same railway’s stock of 40 years ago.

The Great Northern Railway (GNR) Class C1 is a type of 4-4-2 steam locomotive. One, ex GNR 251, later LNER 2800, survives in preservation. Much like their small boiler cousins, they were capable of reaching speeds of up to 90 mph (145 km/h).

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.

The LNER 4-4-2 Atlantic Locomotives. Britain's first Atlantic appeared on the Great Northern Railway (GNR) in 1898 as an enlargement of the ubiquitous 4-4-0 for express work, building 116 examples of various designs.

The Great Northern Railway (GNR) Small Boiler Class C1 is a class of steam locomotive, the first 4-4-2 or Atlantic type in Great Britain. They were designed by Henry Ivatt in 1897. In total 22 were built between 1898 and 1903 at Doncaster Works.

When he left he took with him a set of drawings for Ivatt’s large boilered atlantics (LNER class C1), with which he had been heavily involved in, and constructed his own engines to the same design. The appropriate modifications were marked on the drawings in red ink. The main differences were longer piston stroke and increased boiler pressure.

Designed by H. A. Ivatt and introduced in 1902, the C1 class totalled 81 members, of which one, GNR no 251, LNER no 2800, survives. The last working examples just survived into B.R. days, being withdrawn in 1950.

From June 1914, the entire class became known as simply "C". Most of the rebuilds used 18in x 24in cylinders and Joy valve gear to match the existing simple locomotives. However, 75 J21s were rebuilt using larger 19in diameter cylinders, Stephenson valve gear, and piston valves.
