designed for heavy freight. Introduced in 1911, and designed by John G. Robinson, 126 were built for the GCR prior to the First World War. Including wartime construction for the British Army ROD and the post-war GCR Class 8M, the class and its derivatives totalled 666 locomotives.

and 126 were in traffic by June 1914. During the First World War there were experiments with oil burning 8Ks with larger bogie tenders. Post-war, a further 19 locomotives were built in 1918–21 to a modified design with a larger boiler (GCR class 8M). In 1922 the GCR rebuilt two Class 8M to Class 8K.

After the war, the surviving ROD locomotives were sold to various railway companies, with the GCR itself purchasing 3 in 1919, which were added to its indigenous 8K fleet.

Many of these had short lives with their new owners – the LMS locomotives were all scrapped or sold by the 1930s, and half of the GWR fleet was gone by 1930. However, other GWR engines survived well into the 1950s. The last of 13 locomotives sold to J & A Brown for use on the Richmond Vale railway line, in Australia, was retired in 1973, and 3 locomotives in China were only retired in 1990.

LNER and BR ownership

Upon its formation in 1923 the London and North Eastern Railway inherited a total of 131 class 8K and 17 class 8M locomotives from the Great Central Railway. Under the LNER's ownership the 8Ks became known as Class O4, and the 8Ms as Class O5, although all of the O5s were converted to Class O4s by 1946. They were joined by a further 273 former ROD locomotives purchased in 1923–27, bringing the total LNER O4 fleet to 421 locomotives. Some 92 of these were requisitioned by the War Department in 1941 for use in support of Commonwealth forces in the Middle East, none of which would return to Britain. The O4 locos served widely throughout the LNER system, many being modified to help extend their useful working life on heavy freight trains. Fifty-eight of the class were rebuilt into LNER Thompson Class O1s in 1944–49. 329 LNER O4 locomotives passed to

ownership in 1948. Five locomotives were sold to the Government in 1952 for use in Egypt, and routine withdrawals of BR's class O4s commenced in December 1958. The last examples of the class were withdrawn from operations in the Doncaster area in April 1966, not long before the abandonment of steam altogether.

Models

In 2009 Bachmann Branchline announced a ready-to-run ' 00' scale model of the Class 8K, marketing it under the LNER class name of O4. The models were of preserved 63601, and models of two scrapped examples (BR 63635 and LNER 6190) have since been released. In October 2012, RailSimulator.com released a payware add-on of the GCR 8K, again marketed under its LNER O4 classification, for '' Train Simulator 2013''. It was released as a companion to the Woodhead Line add-on, released earlier in the year, and features sounds from the preserved O4 63601 before its boiler ticket ran out, and includes four scenarios for the Woodhead Line and Quickdrive compatibility.
