railroadclass= 7FTheGreat Central Railway (GCR) Class 8K2-8-0 is a class ofsteam locomotive designed for heavy freight. Introduced in 1911, and designed byJohn G. Robinson , 129 were built by the GCR.The first of the 8K class was outshopped from the GCR's
Gorton workshops in 1911. It was essentially a superheated version of an earlier0-8-0 , the 8A class, with the addition of apony truck . This both supported the greater front end weight and gave a steadier ride. The 8K was introduced to anticipate the increased traffic from the GCR's vast new docks complex atImmingham inNorth East Lincolnshire and by June 1914 126 were in traffic.The GCR Class 8M was similar and in 1922 the GCR rebuilt two Class 8M to Class 8K, taking the total to 131 locomotives.
ROD locomotives
Robust and straight forward, the 2-8-0's steamed well and proved outstandingly reliable, qualities that commended the design to the Ministry of Munitions. Sir
Sam Fay ensured that they became the standard locomotive during theFirst World War as theROD 2-8-0 , used by theRailway Operating Division of theRoyal Engineers .LNER and BR ownership
The
London and North Eastern Railway (LNER) classified the 8K as part of itsLNER Class O4 . The LNER also bought severalROD 2-8-0 s which they added to the O4 Class. Some of the class were converted intoLNER Thompson Class O1 s after 1944. The LNER locomotives passed toBritish Railways (BR) in 1948.Preservation
One of the GCR-built O4s, BR number 63601, is preserved in
Great Britain where it runs on the preserved Great Central Railway at Loughborough. In addition, there are three moreROD 2-8-0 s not used by the GCR inAustralia , two at theDorrigo Steam Railway and Museum and one atRichmond Vale Railway Museum .External links
