The Genealogy of the 2 cylinder ‘SAINTS’
G. J. Churchward started to develop his new designs in 1901, before he took over from William Dean in 1902. His first production express locos were a series of Atlantics and 4-6-0s (2971 - 2990) They all had 6’ 8 1/2” driving wheels, 3’3” bogie wheels, inside steam pipes and 3000 gallon tenders. These appeared in 1905 and were classed as Scotts as they bore the names from Walter Scott’s Waverley novels. Several were built as 4-4-2s and later converted to 4-6-0, with others treated visa-versa, whilst the merits of both wheel arrangements were being gained. 1906 saw the completion of ten further 4-6-0s (2901 - 2910) called ‘The Ladies’. They were fitted with both long or short cone boilers.
They all had the square footplate drop forward of the cylinders and no drop at the cab end. 1907 saw the first of the true Saints, Nos 2911 - 2930. These all had the long cone No 1 boiler with curved footplate drop at front and rear, and carried the names of Saints. The final version appeared in 1911 as the Courts (2931 - 2955).These were visually the same as the Saints but incorporated a number of technical advances. In December 1912 there was a revision of the Company’s numbering scheme and all the above groups were classed as Saints.
These kits are designed for spirit firing with a sufficient amount of detail to provide a robust working model. Some brakegear components are supplied to allow the modeller to add extra detail. The GW 3000 gallon tender which is easy to build is standard. the 3500 gallon version is also available. In common with our other designs, the working valvegear will be a robust, slip eccentric, protected between the frames.
The model is designed to be either 4-6-0 or 4-4-2 and the basic price will build one version. For a few pounds more the extra conversion bits can be purchase to convert from one design to the other, for example exchange rear drivers for the pony.
