About this ebook

Designed by G.J. Churchward, no. 40 was constructed at Swindon in April 1906. It was Swindon’s first 4 cylinder simple engine and was the forerunner of Churchward’s famous 4 cylinder Star Class 4-6-0s. Initially built as a 4-4-2 Atlantic, no. 40 was named North Star in September 1906, rebuilt as a 4-6-0 in 1909, and renumbered 4000 in 1913. Including no. 40, the Star class eventually numbered seventy-three locomotives, all built at Swindon in batches between 1906 and 1923.
In service the Stars proved to be both free-running and reliable locomotives, and for many years were used to haul the Great Western’s top link services, including the world-famous ‘Cornish Riviera Express’. The introduction of the Collett Castle Class 4-6-0s in 1923, and the King Class 4-6-0s in 1927, saw the Stars relegated to secondary passenger, freight and parcels services. A number of Stars were rebuilt by Collett as Castles, including the prototype no. 4000 North Star, but the remaining Stars continued to give good service. At Nationalisation in 1948, no less than forty-seven of these fine locomotives passed into Western Region ownership, the last example, no. 4056 Princess Margaret, being withdrawn in October 1957.
In this book, Laurence Waters charts the history of the class from the prototype, right through to the final workings in October 1957. Using many previously unpublished photographs from the Great Western Trust photographic collection, accompanied by informative captions, every member of the Class is illustrated. This book should appeal to those interested in the history of Great Western locomotive development as well as modellers of the Great Western and Western Region.

    Great Western Star Class Locomotives - Laurence Waters

    THE GREAT WESTERN STAR CLASS 4-6-0S

    Churchward’s four cylinder Star Class 4-6-0s were, for many, years the crack performers on Great Western main line services. They were loved by footplate men and enthusiasts alike, and although these superb free-running locomotives were gradually superseded by Collett’s more powerful Castle and King Class 4-6-0s, the Stars continued to give good service right up until the last working example, No. 4056 Princess Margaret , was withdrawn on 28 October 1957.

    George Jackson Churchward was born in Stoke Gabriel, Devon, on 31 January 1857. After leaving school he began his lifelong career on the railway with an apprenticeship on the South Devon Railway at the Newton Abbot works. On 1 February 1876, the South Devon Railway amalgamated with the Great Western; and in 1877, aged 19, Churchward moved jobs to Swindon, where he was initially employed in the Materials department. He was well thought of at Swindon, and in 1897 after successive promotions he ended up as the Chief Assistant to the then Locomotive Carriage and Wagon Superintendent, William Dean. Dean was not in good health at this time, and by 1898 Churchward was essentially running the Locomotive Department, although technically still Dean’s assistant. Dean officially retired through ill health on 31 May 1902, and on 1 June, Churchward took over as head of the department.

    Much of his early experimental work was centred on devising improvements in the design of the boiler and smokebox as well as the cylinders and valve gear, and also in the individual balancing of all coupled wheels, together with the introduction of lightweight big ends with solid bushes.

    In the year before he officially took over from Dean, Churchward had outlined the need for up to six new ‘standard’ locomotive types that would meet the needs of the traffic department at that time and also of the potential growth in future traffic. Up to this point, Great Western motive power comprised mainly double frame locomotives with the cylinders placed inside the frames. Churchward’s concept was for a series of simple expansion engines with single frames, using Stephenson valve gear, and with the cylinders placed on the outside of the frames. These six new classes’ new locomotives would have standardised cylinders measuring 18 inches in diameter with a 30in stroke, plus 8½in piston valves together with a standardised valve motion, and just two main types of boiler.

    The first on his list was a heavy main line express locomotive with 6ft 8½in driving wheels. It is well known that Churchward had been a great admirer of both American and European locomotive design. American locomotives tended to be simple and basic with high running frames, as opposed to the rather more sophisticated designs of the European locomotives, particularly those running in France. He particularly admired the French 4 cylinder De Glehn compound 4-4-2s, which at this time were considered to be some of the finest express passenger locomotives in Europe. Churchward was to eventually incorporate some of best features of these locomotives into his own designs, but not the compound system, which he had dismissed from an early date. In order to effect a comparison with his own Saint prototypes that were still very much in the development stage, he had persuaded the Great Western to purchase at a cost of about £4,000 a De Glehn Atlantic from the Society Alsacienne de Constructions Mechanique of Belfort. The locomotive was placed in Great Western stock in October 1903. Numbered 102 and named La France, it had 6ft 8½in coupled wheels and a boiler that was similar in size to the Swindon No. 1 boiler, but which operated at a slightly higher pressure of 227lb psi. In 1905 a further two De Glehn Atlantics were purchased by the company, again for testing purposes, being numbered 102 and 103 and named President and Alliance respectively. Interestingly these three French locomotives, although altered over the years by the Great Western, ran on express services until their withdrawal in 1926, 1927 and 1928 respectively.

    In 1902, No. 100, the first of three prototype 2 cylinder Saint class 4-6-0s, with 6ft 8½in coupled wheels, left the factory at Swindon. This unique locomotive was followed by Nos. 98 and 171 in March and December 1903. The importance of these 2 cylinder locomotives cannot be underestimated as they set the standard for express power on the GWR and elsewhere in both performance and design until the advent of the Stars. The history and development of these fine locomotives are described in detail in my book The Great Western Saint Class 4-6-0s.

    With the success of the Saints, Churchward now turned his attention to producing an even more powerful 4-6-0 again with 6ft 8½in driving wheels, but this time with 4 cylinders. Construction of a 4 cylinder simple express passenger locomotive (No. 40) had been authorised by the Great Western Board on 19 July 1905, at an estimated cost of £3,600, but it was not until a year later that the prototype appeared. The engine record sheets show that its actual cost was £3,219 for the locomotive and an extra £1,036 for 3,500 gallon tender No. 1654. Churchward’s various reports to the Directors make interesting reading. He first mentioned the construction of his 4 cylinder prototype in a report to the Directors dated 5 December 1905 regarding the construction of the 2 cylinder Saint Class 4-6-0s. He states: ‘The engine (No. 40) is not yet complete. It is designed with four small simple cylinders with a view to see if the same smoothness of running and economy can be obtained as with the De Glehn compounds without the same amount of complication and cost.’ He goes on to say: ‘I had hoped to postpone the construction of any more heavy express engines until No. 40 had been tested but it is now found that to provide a margin for working heavy services next summer, we should have another ten engines of maximum power. I am recommending a vote for ten of the 4-6-0 class for this purpose (the Saints).’

    In April 1906, No. 40 finally emerged from the works as a 4-4-2, and after extensive testing was allocated to Old Oak Common on 20 June 1906. On 29 June 1906 in yet another report Churchward states, ‘This engine has now been at work for a week or two and the result is very promising indeed.’ This report is interesting
