GWR 4-6-0 âKing James Iâ 6000 Class – GWR
Running number: 6011
Suitable rolling stock: R4669, R4670
In the mid-1920s, with train load sizes increasing to and from the South West, the Great Western Railway were faced with the need for even more powerful locomotives, something that could haul the heavy expresses at an average speed of 60 mph. The problem, however, was that the main routes were limited to a 20 ton axle weight and to counter this, a number of the Great Westernâs routes were upgraded to take an increase in axle weight, including the strengthening of some bridges.
Based on this the Great Westernâs General Manager, Sir Felix Pole, gave his Chief Mechanical Engineer, Charles Collett, permission to proceed with the design and construction of a “Super-Castle”, the result being the King class 4-6-0 design which emerged from Swindon works in June 1927.
Collettâs design increased the length and wheelbase over the Castle class, necessary to accommodate the new WA designated boiler, with both the driving wheels and bogie wheels being reduced in size from that of the Castles. With an increase in boiler working pressure to 250lb, a larger diameter cylinder and a longer stroke, the Great Western promoted the new Kings as âthe most powerful passenger locomotives in the countryâ. Certainly, at 29ft 5in and weighing 89 tons, the class probably represented the limit of the 4-6-0 design.
Initially, 20 locomotives were ordered, the first six being built at Swindon in June and July 1927, followed by the remaining fourteen locomotives between February and July 1928. The final ten locomotives of the class were not to be built for another two years, being constructed between May and August 1930 and they incorporated some minor changes from the earlier engines.
The decision to name the new class after the Kings of England was agreed by Collett in May 1927, being named in reverse chronological order starting from King George V. Only two engines were renamed, 6028 King Henry II becoming King George VI on January 12, 1937 and 6029 King Stephen becoming King Edward VIII on May 14, 1936.
Only being able to operate over the Great Westernâs âDouble Red Routeâ, the Kings were confined to the West of England main line as far as Plymouth, via Newbury and Bristol, as well as the cut-off route from Paddington to Wolverhampton via Bicester. It was over these routes that the Kings came to be associated with the iconic Cornish Riviera Express and Cambrian Coast Express services, regularly reaching speeds of 100mph.
The Kings were gradually replaced on the west of England services by diesel-hydraulic power from 1959 and on the Paddington-Wolverhampton run from 1962. By December 31, 1962 all had been withdrawn from service to face the cutterâs torch. Eventually three of the class survived into preservation; 6000 King George V, 6023 King Edward II and 6024 King Edward I.
Locomotive 6011 King James I was built at Swindon in April 1928 and was allocated to Old Oak Common MPD on May 1, 1928. Over the course of the locomotiveâs lifetime it clocked up 1,718,295 miles in service, before finally being withdrawn on December 18, 1962.
