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 …

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.

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.

GNR Class C1 may refer to either of the following classes of railway locomotive designed for the Great Northern Railway by Henry Ivatt: GNR Class C1 (large boiler), 94 locomotives introduced from 1902, later LNER Class C1; GNR Class C1 (small boiler), 22 locomotives introduced from 1898, later LNER Class C2

Ivatt introduced the 4-4-2 Atlantic type to Britain with his 'Klondike' (LNER C2) type in 1898. In December 1902, he built No. 251 by adapting the design and increasing the boiler diameter from 4ft 8in to 5ft 6in. The GNR classified both types as C1, but the LNER classified the large boiler variation as C1 and the small boiler variation as C2.

Jul 5, 2023 · Britain’s first 4-4-2 ‘Atlantic’ type locomotives, the Great Northern Railway’s (GNR) C1 small and large boiler were the predecessor to Nigel Gresley’s A1, A3 and A4 4-6-2 ‘Pacific’ engines on the East Coast Mainline.

GNR 251 was built at Doncaster in December 1902 as the first example of the C1 class. It was fitted with a superheated boiler in August 1918 and in December 1923 the valve gear was changed to piston valves.

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). They were also known as …

Between 1905 and 1908, sixty large-boilered C1s were built with simple expansion. These locomotives replaced the lever reversing gear with a screw reverse which was assisted by air pressure. The firebox had to be slightly re-designed so …
