The GNR Classes D2 and D3 were two classes of 51 4-4-0 steam locomotives designed by Henry Ivatt for the Great Northern Railway (GNR). They were the first 4-4-0s to be introduced by the GNR, and Ivatt's first original design for the railway as well. [1]

GNR Class D2/LNER Class D4

The first member, No. 400, emerged from Doncaster Works in December 1896. Between May 1897 and December 1899, fifty more locomotives were built. The last ten, Nos. 1351-1360 (LNER Nos. 4351–4360) were built with a raised running plate above the coupling rods to match the Small Atlantics that were being introduced at this time. Unlike most 4-4-0s of the era, the D2s were intended for secondary duties from their conception. As well as stopping passenger trains, the D2s could also be seen as pilots to the Stirling Singles on heavy express trains. Another duty for the class was light express passenger trains.

The D2s initially suffered from their bogies being prone to cracking, and between 1909 and 1921 extra plates were added to replace their bogie frames, which were also 2.5 inches deeper. After 1921, their frames were strengthened further and more plates were placed within them. Under the LNER, the D2s were reclassified as D4s. Following the Grouping, both they and the D3s moved to former Great Central Railway and North Eastern Railway sheds.

GNR Class D3/LNER Class D3

In 1912, Nigel Gresley replaced Ivatt as chief mechanical engineer for the GNR. That same year, he introduced a new 4 ft 8 in boiler for the D2s and the GNR J5 0-6-0s. Although the firebox was shorter, the overall area of 105 square feet was two square feet more than the D2s. The first member to be rebuilt was No. 1359 in November 1912, six months after J5 No. 1163. The rebuild also involved shortening the chimney and raising the boiler. By 1923, six as-built D2s (now classified as D4s) remained. The last member to be rebuilt was No. 4358 in June 1928. In 1923, No. 1305N was rebuilt with slightly larger tubes and a larger firebox. In this form, it became part of the LNER D2 Class, which had seventy other previous locomotives built between 1898 and 1909. In 1926, No. 4320 was also rebuilt, bringing a class total of seventy-two D2s. [2] The D3s meanwhile had forty-nine members left in service.

In the 1930s, the Stainmore Route in County Durham, which ran from Darlington to Penrith, was in need of more locomotives to replace the LNER D23 Class 4-4-0s. Initially LNER J21 Class engines had been tried, but these tended to have motion failures, particularly after descending the line's banks due to a habit drivers had when it came to driving the class in these areas. It was decided to test D3s on the line to see if they would perform better. To do so, they were fitted with larger cabs and side windows for better crew protection. However, the class proved to be unsuited for the Stainmore line. [3] In 1944, No. 4075 was fitted with a Thompson cab and, after World War II, was painted in LNER apple green, the only member of her class to carry this livery.

Withdrawals

Withdrawals began as early as 1935, with Nos. 4308 and 4360 being taken out of service in October. By the start of World War II, only thirty-five were left, though only No. 4304 was withdrawn during the war in 1942. Mass withdrawals picked up starting in February 1946. However, thirty-one members did survive long enough to get renumbered under Thompson's renumbering scheme. Nineteen survived into British Railways ownership in 1948, but only three members survived long enough to get renumbered. The final member withdrawn was No. 62000 on 18 October 1951, being the last surviving GNR 4-4-0 in operation. All members of the class were ultimately scrapped.

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. The class were commonly known as 'Klondykes' [sic], after the 1897 Klondike gold rush. They could reach speeds of up to 90 mph. They were also known as Small Atlantics.

<span class="mw-page-title-main">LNER Gresley Classes A1 and A3</span> Class of 4-6-2 pacific locomotive designed by Sir Nigel Gresley

The London and North Eastern Railway LNER Gresley Classes A1 and A3 locomotives represented two distinct stages in the history of the British 4-6-2 "Pacific" steam locomotives designed by Nigel Gresley. They were designed for main line passenger services and later express passenger services, initially on the Great Northern Railway (GNR), a constituent company of the London and North Eastern Railway after the amalgamation of 1923, for which they became a standard design. The change in class designation to A3 reflected the fitting to the same chassis of a higher pressure boiler with a greater superheating surface and a small reduction in cylinder diameter, leading to an increase in locomotive weight. Eventually all of the A1 locomotives were rebuilt, most to A3 specifications, but no. 4470 was completely rebuilt as Class A1/1.

<span class="mw-page-title-main">NER Class C1</span>

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.

<span class="mw-page-title-main">GNR 521 Class</span>

The Great Northern Railway 521 Class was a class of 0-6-0 steam locomotives, introduced in 1911. They were designed by Henry Ivatt for goods traffic. From 1912 to 1922 further examples, slightly modified by Nigel Gresley, were built and designated 536 Class. The most obvious difference was in the front sandboxes. These were below the running plate on the 521 but above it and merged with the front splashers, on the 536. The boiler and firebox were also moved back, thus resulting in a shortened cab. The London and North Eastern Railway classified them both as J6.

<span class="mw-page-title-main">NER Class S3</span>

The North Eastern Railway Class S3, classified B16 by the LNER, was a class of 4-6-0 steam locomotive designed for mixed traffic work. It was designed by Vincent Raven and introduced in 1920. The earlier members of this class were fitted with Westinghouse Brakes - all of this equipment was removed during the 1930s.

<span class="mw-page-title-main">GNR Class J23</span>

The Great Northern Railway Class J23 was a class of 0-6-0T steam locomotive. They had long side tanks that came to the front of the smokebox, which sloped forwards to improve visibility and had a recess cut in to aid maintenance. Forty were built by the Great Northern Railway (GNR) between 1913 and 1922, with a further 62 being added by the London and North Eastern Railway (LNER) between 1924 and 1939. They were given the nickname "Submarines" due to their long tanks.

<span class="mw-page-title-main">GNR Class C1 (large boiler)</span>

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 Large Atlantics.

The GER Class F48 was a class of sixty 0-6-0 steam tender locomotives designed by James Holden for the Great Eastern Railway in Great Britain. They passed to the London and North Eastern Railway at the grouping in 1923 and received the LNER classification J16.

<span class="mw-page-title-main">GER Class T19</span>

The GER Class T19 was a class of 2-4-0 steam tender locomotives designed by James Holden for the Great Eastern Railway. Some were later rebuilt with larger boilers while others were rebuilt with both larger boilers and a 4-4-0 wheel arrangement. Unusually, both the 2-4-0 and 4-4-0 rebuilds were classified as GER Class T19 Rebuilt. All the 2-4-0s had been withdrawn by 1920 so only the 4-4-0s passed to the London and North Eastern Railway in 1923 and these became the LNER Class D13.

The LMS (Northern Counties Committee)Class B3 4-4-0 passenger steam locomotives were rebuilds of Belfast and Northern Counties Railway (BNCR) two-cylinder compound locomotives. They operated services throughout the NCC's 5 ft 3 in (1,600 mm) broad gauge system in the north-east of Ireland.

The Midland Railway Johnson 0-6-0 were a class of locomotives serving Britain's Midland Railway system in the late 19th and early 20th centuries. Between 1875 and 1908 the Midland Railway, under the control of locomotive superintendents Samuel Waite Johnson and Richard Deeley, ordered 935 goods tender engines of 0-6-0 type, both from the railway's own shops at Derby and various external suppliers. Although there were many variations between different batches both as delivered and as successively rebuilt, all 935 can be regarded as a single series, one of the largest classes of engine on Britain's railways. The locomotives served as late as 1964, but none of them now survive.

The London and North Eastern Railway (LNER) operated various classes steam locomotives with a 4-6-2 wheel arrangement. The LNER operated more pacifics than any other of the Big Four British railway companies, and they were mostly used for express passenger work along the East Coast Main Line, though later in their lives many were displaced to other lines.

Although overshadowed by the later and more famous steam locomotives that John G. Robinson would go on to design, the Great Central Railway Class 11B 4-4-0 Express Passenger engines were a successful class which totalled 40. Built from 1901 to 1903, in later rebuilt form as 11D, some 11Bs would last in service until 1950. Railwaymen continued to refer to the class as "11B" even after all were rebuilt to 11D. Being contemporary with and to some extent the 4-4-0 version of Robinson's much more numerous 0-6-0 goods class 9J, which were known as "Pom-Poms", the 11Bs acquired the nickname "Pom-Pom Bogies". The London & North Eastern Railway classified the 11Bs, along with their 11C and 11D rebuilds, as Class D9.

The Great Northern Railway J4 Class was a class of 322 0-6-0 steam locomotives, introduced in 1882 designed by Patrick Stirling for goods traffic. Just over half of these were rebuilt by Nigel Gresley to a design by Henry Ivatt between 1912 and 1929.

<span class="mw-page-title-main">Midland Railway 1833 Class</span>

The Midland Railway 1833 Class was a class of thirty 0-4-4T steam locomotives. They are sometimes included with the earlier 1823 Class or the later 2228 Class.
