The Great Western Railway (GWR) 3000 Class was a class of 2-8-0 steam locomotive consisting of the ex-Railway Operating Division ROD 2-8-0. These were built by North British Locomotive Co. between 1917 and 1918. No examples have been preserved.

Contents

Initial loans and purchase

The GWR borrowed several ROD 2-8-0s during the First World War but these were returned to the government after the end of the war. In 1919, GWR bought 20 virtually new RODs, and numbered them 3000–19. A further 84 were hired in July 1919, and were numbered 3020-99 and 6000–3, but these were returned in October 1922. In 1925, the GWR bought 80 engines (including some previously hired) and numbered them 3020–99.

Overhaul and sorting

In 1926/7 the GWR sorted the eighty RODs bought in 1925 which had been given nos. 3020–99 into two batches, which involved considerable renumbering. The worst fifty were touched up and returned to traffic with steel fireboxes and painted the original R.O.D. black and renumbered 3050–99; [1] they were run until they failed, when they were withdrawn – after July 1930, only one remained, being withdrawn the following year. [2] The best thirty were thoroughly overhauled, fitted with copper fireboxes and painted G.W. standard green, [1] they also acquired Swindon fittings, including top feed and brass safety valve casing, and were renumbered 3020–49. Nos. 3000–19 (bought 1919) were also overhauled similarly to the new nos. 3020–49 between 1927 and 1929, but were not further renumbered. [2] The leading dimensions of the GWR 3000 Class were the same as the GCR Class 8K except that the GWR increased the boiler pressure to 185 psi (1,280 kPa) which increased the tractive effort from 31,327 lbf (139,350 N) to 32,197 lbf (143,220 N).

World War II

The GWR borrowed 30 Class O4 from the LNER in November 1940, of which two were returned the following April; ten were returned in July–August 1942 and the rest in January–February 1943. On the GWR, they retained their LNER numbers, which were scattered between 5391 and 6639. [3] Three of these had been hired by the GWR between 1919 and 1922:

No. 3040 at Oxford Locomotive Depot 22 February 1953

Forty-six of the RODs entered British Railways service in 1948. Five locomotives (numbers 3011, 3015, 3024, 3036 and 3041) were still in service in 1957 [6] and of these, nos. 3036/41 were withdrawn in March 1958, the others in October the same year. [7] None of the GWR RODs has survived to preservation.

Modelling

In November 2011, Bachmann released a OO gauge ready to run model of the 3000 class. This complements kits in various gauges.

The Great Western Railway (GWR) 2600 Class or Aberdare Class was a class of 2-6-0 steam locomotive built between 1900 and 1907. They were a freight version of the 3300 and 4100 classes, both 4-4-0 locomotives. Therefore the design was adapted and became a 2-6-0 type; the resulting locomotives were used for hauling coal trains between Aberdare and Swindon.

In total 15 were built, 10 by the NER between 1909 and 1910, and a further five in 1925 by the London and North Eastern Railway (LNER). They had three cylinders with divided drive: the inside cylinder driving the leading axle, the outside cylinders driving the centre.

The Class EF1 was a class of electrically powered locomotives built by the North Eastern Railway from 1914. They were built to haul coal trains from the mines at Shildon to the docks at Middlesbrough. In common with other LNER electric locomotives, no classification was given to these locomotives until 4 October 1945, when nos. 3-12 were all classified EB1 although only no. 11 was actually modified for banking. It was expected that all the locomotives would be similarly modified, but this did not happen, and the remaining locos were classified as EF1.

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 Great Central Railway (GCR) Class 8A was a class of 0-8-0 steam locomotive built between 1902 and 1911 for handling heavy coal trains over the Pennines. They all passed to the LNER in 1923, who redesignated them Class Q4. They were withdrawn from service between 1934 and 1951.

The NER Class P1 was a class of 0-6-0 steam locomotives of the North Eastern Railway. Class P1 was a development of Class P, having a boiler four inches longer, and a firebox six inches longer. To accommodate these, the wheelbase was increased by nine inches. The cylinder stroke was also increased by two inches. None survived into preservation

The NER 38 Class was a class of 4-4-0 steam locomotives designed by Alexander McDonnell for the North Eastern Railway. Twenty-eight were built in 1884–5, and remained in service until 1915–23.

The GWR 378 Class was a class of 30 standard-gauge 2-2-2 steam locomotives on the Great Western Railway in Britain. They were introduced in 1866, and the class remained intact until 1898. Several were altered to the 0-6-0 wheel arrangement, and the last was withdrawn from service in 1920.

GCR Class 9P was a design of four-cylinder steam locomotive of the 4-6-0 wheel arrangement built for hauling express passenger trains on the Great Central Railway in England. A total of six were built: one in 1917, and five in 1920. They were sometimes known as the Lord Faringdon class, from the name of the first one built.
