The Great Western Railway 1000 Class or County Class was a class of 4-6-0 steam locomotive. Thirty examples were built between 1945 and 1947, but all were withdrawn and scrapped in the early 1960s. A replica locomotive is under construction.
These locomotives were the final and most powerful development of the two-cylinder Saint Class introduced in 1901 and included several features that had already been used on the successful Modified Hall class. [2]
The Chief Mechanical Engineer of the GWR Frederick W. Hawksworth had hoped to design a new 4-6-2 (Pacific) express locomotive for post war traffic, when he took up office in 1941 but had been prevented by the war from doing so. [3] This scheme was not entirely dead in 1945 when he was given the authority to build another batch of mixed-traffic 4-6-0s. Rather than build more examples of existing designs, Hawksworth introduced the County Class as a testbed for a number of the ideas he hoped to incorporate into the Pacific at a later date. [4] Hawksworth was not subsequently allowed to build his Pacific, as there was no need for further express passenger locomotives.
In addition to the innovations already adopted for the Modified Hall class, the new class contained several further changes from usual Great Western practice including the use of double chimneys on certain members and a high boiler pressure of 280psi (although this was later lowered in an attempt to reduce maintenance costs). The boiler was a development that used the tooling for the LMS Stanier Class 8F boiler, Hawksworth being able to study this design closely when 8Fs were being built at Swindon as part of the war effort. [2] The class initially had a tractive effort of 32,580 lbf (144.92 kN), which was =1,000 lbf (4.45 kN) greater than a Castle Class locomotive, although the tractive effort was reduced to 29,090 lbf (129.40 kN) when the boiler pressure was lowered. The class had continuous splashers over the driving wheels and, when named, straight nameplates, making them immediately recognisable from other 4-6-0 classes. They were also fitted with Hawksworth's 4,000 imp gal (18,000 l; 4,800 US gal) slab-sided tenders, but the County tenders had a water tank six inches wider than the tenders built for the Modified Halls and retro-fitted to many earlier designs.
Some of the early design studies for what became the County included outside Walschaerts valve gear which would have been a major break from traditional GWR designs. In the event the standard inside Stephenson link motion of the Churchward and Collett two cylinder classes was used. The GWR 1500 Class, also designed by Hawksworth, used outside Walschaerts [lower-roman 1] as did the steam railcar units designed under Churchward and the narrow gauge Vale of Rheidol 2-6-2T.
The first batch of twenty were built at Swindon Works and delivered between August 1945 and March 1946 (Lot No. 354). They were originally unnamed and were planned to be numbered in the 9900 series, but this was changed to 1000-1019 before introduction. [2] A second batch of ten further locomotives (1020-1029) were built between April 1946 and April 1947 (Swindon Lot 358). The second batch were given names English and Welsh Counties previously used on the GWR 3800 Class of 4-4-0 tender locomotives that were part of George Jackson Churchward's locomotive standardisation programme in the early days of the 20th century.
The Counties had a mixed reception: some traditionalists regarded them as ‘non-standard, expensive and unnecessary,’ [5] others considered them a successful, free steaming design, well suited to express or freight work and a fitting finale to GW two-cylinder 4-6-0 development. According to O.S. Nock ‘their best and really brilliant work was done north of Wolverhampton where they ran very heavy trains with conspicuous success.’ [6]
After the nationalisation of Britain's railways in 1948 all 30 Counties continued to do useful work throughout the Western Region of British Railways, working with Castles on expresses to and from Paddington as well as more menial freight and parcels tasks. BR gave the Counties the power classification 6MT. [7] Speedometers were fitted to the class from 1950 and modified double chimneys from 1956.
Withdrawals of the class took place between September 1962 and November 1964. No. 1011 County of Chester was the last of the class withdrawn. It was placed in storage before being sold to Cashmore's scrapyard in Newport where it was cut up in March 1965. All were scrapped.

No locomotives of this class survived into preservation. However a replica is being built at the Didcot Railway Centre, home of the Great Western Society. When completed it will take the name and number of No. 1014 County of Glamorgan in recognition of the late Dai Woodham's Barry Scrapyard in Glamorganshire from which many withdrawn steam locomotives were saved for preservation. Also Glamorganshire County Council donated the frames and boiler for the project. The replica is based around the frames from Modified Hall Class 7927 Willington Hall and the boiler from LMS Stanier 8F 48518. The boiler from the Hall will be used in the replica Grange project at the Llangollen Railway. It will also have a number of smaller original parts off scrapped County locomotives including the chimney from 1006 County of Cornwall.
Hornby Railways manufacture a model of the 10xx in OO gauge. This model was originally made by Dapol.

The Great Western Railway 4000 or Star were a class of 4-cylinder 4-6-0 passenger steam locomotives designed by George Jackson Churchward for the Great Western Railway (GWR) in 1906 and introduced from early 1907. The prototype was built as a 4-4-2 Atlantic. They proved to be a successful design which handled the heaviest long-distance express trains, reaching top speeds of 90 mph (145 km/h), and established the design principles for GWR 4-cylinder classes over the next twenty-five years.
The Great Bear, number 111, was a locomotive of the Great Western Railway. It was the first 4-6-2 (Pacific) locomotive used on a railway in Great Britain, and the only one of its type built by the GWR.
George Jackson Churchward was an English railway engineer, and was chief mechanical engineer of the Great Western Railway (GWR) in the United Kingdom from 1902 to 1922.
The GWR 4100 Class was a class of steam locomotives in the Great Western Railway (GWR) of the United Kingdom.
The Great Western Railway 3252 or Duke Class were 4-4-0 steam locomotives with outside frames and parallel domed boilers. They were built in five batches between 1895 and 1899 for express passenger train work in Devon and Cornwall. William Dean was their designer, possibly with the collaboration of his assistant, George Jackson Churchward. Four prototype 4-4-0s, of the Armstrong Class, had already been built in 1894.
The Bulldog and Bird classes were double-framed inside cylinder 4-4-0 steam locomotives used for passenger services on the Great Western Railway. The Bird Class were a development of the Bulldogs with strengthened outside frames, of which a total of fifteen were built. A total of 121 Bulldogs were built new, with a further twenty rebuilt from Duke Class locomotives. Thirty Bulldogs were later rebuilt as Earl Class locomotives and renumbered 3265, 3200-3228.
The Great Western Railway 3800 Class, also known as the County Class, were a class of 4-4-0 steam locomotives for express passenger train work introduced in 1904 in a batch of ten. Two more batches followed in 1906 and 1912 with minor differences. They were designed by George Jackson Churchward, who used standard components to produce a four-coupled version of his Saint Class 4-6-0s.
The Great Western Railway 2900 Class or Saint Class, which was built by the Great Western Railway's Swindon Works, incorporated several series of 2-cylinder passenger steam locomotives designed by George Jackson Churchward and built between 1902 and 1913 with differences in the dimensions. The majority of these were built as 4-6-0 locomotives; but thirteen examples were built as 4-4-2. They proved to be a highly successful class which established the design principles for GWR 2-cylinder classes over the next fifty years, and influenced similar classes on other British railways.
The Great Western Railway 4900 Class or Hall Class is a class of 4-6-0 mixed-traffic steam locomotives designed by Charles Collett for the Great Western Railway. A total of 259 were built at Swindon Works, numbered 4900–4999, 5900–5999 and 6900–6958. The LMS Stanier Class 5 4-6-0 and LNER Thompson Class B1 both drew heavily on design features of the Hall Class. After nationalisation in 1948, British Railways gave them the power classification 5MT.
The Great Western Railway (GWR) 6800 Class or Grange Class was a mixed-traffic class of 4-6-0 steam locomotive, built to replace the GWR 4300 Class 2-6-0. There were 80 in the class, all built at the Swindon works, using some reconditioned parts from withdrawn 4300 Class locomotives.
The Great Western Railway (GWR) 6959 or Modified Hall Class is a class of 4-6-0 steam locomotive. They were a development by Frederick Hawksworth of Charles Collett's earlier Hall Class named after English and Welsh country houses.
The Great Western Railway (GWR) 2800 Class is a class of Churchward-designed 2-8-0 steam locomotive.
The Great Western Railway (GWR) 6000 Class or King Class is a class of 4-6-0 steam locomotives designed for express passenger work and introduced in 1927. They were the largest locomotives built by the GWR, apart from the unique Pacific. The class was named after kings of the United Kingdom and of England, beginning with the then reigning monarch, King George V, and going back through history. They handled the principal GWR expresses on the main line from London to the West of England and on the Chiltern line to Birmingham and Wolverhampton, until 1962 when the class was withdrawn.
The Great Western Railway (GWR) 4300 Class is a class of 2-6-0 (mogul) steam locomotives, designed by G.J. Churchward for mixed traffic duties. 342 were built from 1911–1932.
Charles Benjamin Collett was Chief Mechanical Engineer of the Great Western Railway from 1922 to 1941. He designed the GWR's 4-6-0 Castle and King Class express passenger locomotives.
Frederick William Hawksworth, was the last Chief Mechanical Engineer of the Great Western Railway (GWR).
The Great Western Railway (GWR) 4700 Class was a class of nine 2-8-0 steam locomotives, designed by George Jackson Churchward. They were introduced in 1919 for heavy mixed-traffic work. Although primarily designed for fast freight, the class also sometimes hauled passenger trains, notably heavy holiday expresses in the summer months. They were called "Night Owls" because they were primarily designed to haul goods during the night and they could be seen simmering in the daylight, awaiting their nocturnal duties.
The Dean Single, 3031 Class, or Achilles Class was a type of steam locomotive built by the British Great Western Railway between 1891 and 1899. They were designed by William Dean for passenger work. The first 30 members of the class were built as 2-2-2s of the 3001 Class.
No.6880 Betton Grange is a steam locomotive which is under construction as a "new-build" project, originally based on the Llangollen Railway in Denbighshire, Wales, then subsequently at Tyseley Locomotive Works. Described as "building the 81st Grange", the project started in 1998, and the locomotive was earlier expected to be operational by 2013, but subsequently by Autumn 2021. All of the original GWR 6800 Class Grange locomotives were withdrawn for scrap by the end of 1965; this project is a creation, from an assemblage of original GWR and newly manufactured components, of a member of this class.
La France, number 102, was a locomotive of the Great Western Railway. It was bought by G.J. Churchward to evaluate French locomotive practice, and particularly the effect of compounding.
