LNER O4/1 Rod (GCR 8K)


The GCR 8k or more widely know as LNER O4 Rod is a heavy freight locomotive designed by John G. Robinson CME of the Great Central Railway in 1911. The initial design was to haul coal traffic to the new docks at Immingham. The design would go onto become one of the most successful British steam loco designs. The design was chosen by the Railway Operating division (ROD) as the standard heavy freight loco for WW1. This is where the design became known as RODS. A number of O4 Rods where also called up for service in WW2. LNER at their height owned 421 O4 Rod locomotives, the class virtually fulfilled all of the LNER heavy mineral locomotive requirements. At the formation of British Railways 278 O4 Rods where inherited along with 51 O4 rebuilds. The last Belpaire type O4 ROD was withdrawn in February 1966.
