The War Department (WD) "Austerity" 2-8-0 is a type of heavy freight steam locomotive that was introduced in 1943 for war service. A total of 935 were built, making this one of the most-produced classes of British steam locomotive. They were nicknamed Ozzies by the railwaymen. [1]

Overview

The Austerity 2-8-0 was based on the LMS Class 8F, which until that point had been the government's standard design. Various modifications were made to the 8F design by Robert Riddles in order to prioritise low cost over design life. These included a boiler of simpler construction which was parallel rather than tapered and a round-topped firebox rather than a Belpaire firebox. The firebox was made of steel rather than the rarer and more expensive copper.[ citation needed ]

The North British Locomotive Company (NBL) of Glasgow built 545 (split between their two works at Hyde Park and Queen's Park) and the Vulcan Foundry (VF) of Newton-le-Willows, Lancashire, built 390. North British also built a larger 2-10-0 version.

WD nos. 800–879 were ordered as LMS Class 8F. No. 9312, the last one built, was named Vulcan when new. NBL builder's plates were not all in correct sequence, and were mixed up between the two works as well as between batches. All locomotives had their WD numbers increased by 70000 prior to shipping to mainland Europe; those completed after 5 September 1944 carried their 70000 series numbers from new. All but three (WD nos. 77223, 77369 and 79250) saw service with the British Army in mainland Europe after D-Day. [2] [3]

Post-war disposal

After the end of the conflict, the War Department disposed of 930 locomotives (Two engines being retained by the War Department and three being scrapped).

200 were sold to the LNER, which classified them as "Class O7" and numbered them 3000–3199. In 1948, 533 more were purchased by the British Transport Commission. [4]

With the formation of British Railways, the 733 locomotives were renumbered into the 90000–90732 series. Only one of those, No. 90732, was named, becoming Vulcan, after the Vulcan Foundry where many of the locomotives were built.

In 1946, 12 were exported to the British colony of Hong Kong to work the Kowloon–Canton Railway. Six were scrapped in 1956, but the final two survived until September 1962.

The other 184 locomotives remained in mainland Europe, mostly working in and around the Netherlands for Nederlandse Spoorwegen.

Finally, one went to the USATC (WD no. 79189) in an exchange for an USATC S160 Class locomotive in the postwar exchange of WD and USATC locomotives.

Postwar WD service

Two locomotives continued to be held in WD stock, seeing service on the Longmoor Military Railway in Hampshire, along with two of the WD Austerity 2-10-0s and other smaller locomotives. In the WD 1957 renumbering scheme, they were renumbered 400/1. Details were as follows:

Accidents and incidents

Preservation

One WD 2-8-0 has survived. Vulcan Foundry works No. 5200 was repatriated from Sweden to the Keighley and Worth Valley Railway. It was SJ Class G11 number 1931. It was overhauled to its original condition, finished in 2007, which involved building a new cab and tender, to become BR "No. 90733". After test runs, 90733 ran its first passenger train on Monday 23 July 2007. [9] [10] [11]

The steam locomotives of British Railways were used by British Railways over the period 1948–1968. The vast majority of these were inherited from its four constituent companies, the "Big Four".

The London and North Eastern Railway (LNER) produced several classes of locomotive, mostly to the designs of Nigel Gresley, characterised by a three-cylinder layout with a parallel boiler and round-topped firebox. It produced the most famous locomotive of its day, 4468 'Mallard', the holder of the world steam locomotive speed record. It also built the world-famous 4472 'Flying Scotsman'. However, its locomotive inheritance was much greater than just the 'A4 Class', it also produced highly successful mixed-traffic and freight designs.

<span class="mw-page-title-main">1948 Locomotive Exchange Trials</span>

The 1948 Locomotive Exchange Trials were organised by the newly nationalised British Railways (BR). Locomotives from the former "Big Four" constituent companies were transferred to and worked on other regions. Officially, these comparisons were to identify the best qualities of the four different schools of thought of locomotive design so that they could be used in the planned BR standard designs. However, the testing had little scientific rigour, and political influence meant that LMS practice was largely followed by the new standard designs regardless. However, the trials were useful publicity for BR to show the unity of the new British Railways. To record the locomotive performances, one of three dynamometer cars were included in the train directly behind the locomotive.

<span class="mw-page-title-main">BR ex-WD Austerity 2-8-0</span> Steam locomotive

The British Railways (BR) ex-WD Austerity 2-8-0 was a class of 733 2-8-0 steam locomotives designed for heavy freight. These locomotives of the WD Austerity 2-8-0 type had been constructed by the War Department, as war locomotives 1943–1945. After the war, they were surplus and so in 1946 the LNER bought 200 of them, classifying them as LNER Class O7, and by the end of 1947 when the LNER was nationalised, had taken another 278 O7s on loan. After nationalisation, BR purchased 533 more 2-8-0s, including all of those on loan, giving a class total of 733. As many of these needed overhauling before being put to work, they were activated slowly. BR chose to reclassify from LNER Class O7 and renumbered them from the 6xxxx LNER series in the 90000–732 series for BR standard designs.

GCR Class 8G was a class of 10 two-cylinder steam locomotives of the 4-6-0 wheel arrangement built in 1906 for the Great Central Railway.
