![]() Initially, the newly nationalised network continued to be run as four different concerns, and pursued the policy of building of well-established designs. Locomotives built by BR to Big Four designs Plus another 200 examples of LNER Class O7, later renumbered 90000-100,422-520 The ex-WD Hunslet Austerity 0-6-0STs were ex- LNER Class J94 locomotives and are included in the total of LNER locomotives inherited. Of the eight WD ex-LMS Fowler Class 3F 0-6-0Ts exported to France, the five survivors were repatriated in 1948, and resumed their original numbers in the sequence of LMS Fowler Class 3F locomotives (albeit with the additional 40000 that identified ex-LMS locomotives under BR ownership). The third type, of which it had no other examples, were the 25 of the WD Austerity 2-10-0s. The ex-LNER locomotives were later renumbered from the ex-LNER 6xxxx series into the BR series as 90000-90100, 90422-90520. Additionally, it had acquired 200 ex- LNER Class O7 2-8-0s of the WD Austerity 2-8-0 type, to which it added another 533 examples. BR had inherited 556 ex- LMS Stanier Class 8F 2-8-0s, and added 39 in 1949 and an additional three in 1957, bringing the class total to 666. For two of these types, BR was adding to two classes it already had. These had been in use on railways in Great Britain and elsewhere in Europe during the Second World War. also purchased 620 locomotives of three types from the War Department. In addition to the inherited and new-build locomotives, B.R. Locomotives acquired from the War Department 553 ex-WD Austerity 2-8-0s were acquired from the War Department. Mixed traffic locomotives had power in the range of classes 2–6. for the LMS Black Five locomotives, LMS 5P5F became BR 5MT. A slight change from the LMS system saw those where the freight classification ( x) equalled the passenger classification (also x) reclassified as xMT, MT standing for mixed-traffic, e.g. Many locomotives were used for both roles, in which case they were given two class numbers, the P-rating first e.g. Freight power ranged from 0–9, passenger from 0–8. Each locomotive class was given a number 0–9 that signified its power, 0 for the least powerful and 9 for the most, with a suffix of F or P, indicating freight and passenger roles respectively. There were some exceptions though.īR adopted a slightly modified version of the LMS classification system, itself based on the Midland Railway's system. Generally ex-GWR locomotives retained their numbers (and hence were able to retain their cast brass number plates) and it was decided to add 30000 to the Southern numbers, 40000 to the LMS numbers and 60000 to the LNER numbers. Main article: British Rail locomotive and multiple unit numbering and classificationĪfter initially using letter prefixes (E for ex-LNER, M for ex-LMS, S for ex-SR, and W for ex-GWR locomotives, as used for other inherited rolling stock), a numbering scheme was decided on in March 1948. The 1948 Locomotive Exchange Trials compared locomotives from each company against each other. In addition, a handful of locomotives were inherited from minor constituents. Locomotives of the London and North Eastern Railway specifically List of LNER locomotives as of 31 December 1947.Locomotives of the London, Midland and Scottish Railway specifically List of LMS locomotives as of 31 December 1947.Locomotives of the Southern Railway specifically List of Southern Railway locomotives as of 31 December 1947.Locomotives of the Great Western Railway specifically List of GWR locomotives as of 31 December 1947.These had generally standardised their own designs. Locomotives inherited from constituent companies Ī wide variety of locomotives was acquired from the four major constituent companies. It inherited a wide legacy of locomotives and rolling stock, much of which needed replacing due to the ravages of World War II. These locomotives had short working lives, some as little as five years, because of the decision to end the use of steam traction by 1968, against a design life of over 30 years and a theoretical final withdrawal date of between 19.īritish Railways was created on 1 January 1948 principally by the merger of the " Big Four" grouped railway companies: the Great Western Railway (GWR), the London, Midland and Scottish Railway (LMS), the London and North Eastern Railway (LNER) and the Southern Railway (SR). In addition, BR built 2,537 steam locomotives in the period 1948–1960, 1,538 to pre-nationalisation designs and 999 to its own standard designs. The vast majority of these were inherited from its four constituent companies, the " Big Four". The steam locomotives of British Railways were used by British Railways over the period 1948–1968. 6833 Calcot Grange, a 4-6-0 Grange class steam locomotive, at Bristol Temple Meads railway station Steam locomotives used under British Railways (1948 - 1968)Įx- Great Western Railway No.
