BR 2-8-0 Class O1 - Late BR
Product Code: R3090
The Thompson Class O I locomotive was introduced in 1944 as a re-build of the Great Central Railway (GCR) Class 8K 2-8-0 heavy freight locomotive designed by John George Robinson in 1911. Robinson was a Chief Mechanical Engineer (CME) of the GCR Gorton Works, Manchester from 1902 until he was succeeded by Nigel Gresley in 1922.
The 2-8-0 confirguration quickly became the standard for heavy freight steam locomotives in the early part of the 20th Century. A total of 521 Class 8K were built, 130 at GCR Gorton Works, Manchester and the remainder built by other companies. The Class was adopted by the Railways Operating Department during WWI for use in Europe.
In 1923 the GCR was merged with the Machester, Sheffield and Lincolnshire Railway to form the London & North Eastern Railway (LNER) and the locomotive was re-classified as LNER Class O4.
Following the sudden death of Sir Nigel Gresley in 1941, Edward Thompson was appointed as CME to the LNER where he immediately started a badly needed programme of reform and standardisation, discarding many of his predecessors designs and methods.
Due to wartime restrictions on the building of new locomotives it was decided to rebuild some on the Class O4s to meet the need for heavy freight locomotives. A total of 58 were rebuilt between 1944 and 1949, and re-classified as Thompson Class OI, the last being number 63856 in October 1949 for the newly nationalised British Railways (BR).
The main modifications to the original GCR Class 8K design was the incorporation of a standard LNER 100A boiler, Walschaerts valve gear and new cylinders. It weighed 73 tons 6 cwt plus a tender of 48 tons 6 cwt.
The locomotives passed to BR Eastern and North Eastern Regions on the 1st January 1948 and were given BR running numbers in the range of 63570-63920. However, this range included many unrebuilt O4s. Withdrawal of the Class began in the late 1950s with the final withdrawals from the Doncaster area in April 1966.
The locomotive represented in this pack, BR No.63789 was outshopped as a Robinson Class O4 from GCR Gorton Works in December 1912 and rebuilt in January 1946 when it was re0numbered as 6216. On passing to BR in 1948 it was re-numbered yet again as 63789 and was finally withdrawn from service in November 1962.
