[edit] Prototypes

Three prototype locomotives were constructed by the GWR in 1902 and 1903. The first prototype, numbered 100, was built initially with a parallel boiler, which was replaced with a half-cone boiler, and then the first superheated half-cone boiler in 1910. G J Churchward had studied American boiler design, but he was also influenced by continental practice in efficient motion design. From the Société Alsacienne de Constructions Mécaniques (SACM) a De Glehn 4-4-2 compound engine was ordered for comparative trials on the GWR.[1]

Number 98, the second prototype locomotive, was built with a half-cone boiler and a re-designed valve gear layout and cylinders. Valve diameters were increased from 6½ inches (165 mm) to 10 inches (254 mm).[1]

Locomotive no. 171, the third prototype, was built as a 4-6-0 but was soon converted to 4-4-2 for the De Glehn trials. Boiler pressure was increased to 225 psi (1.55 MPa).[1]

Even whilst 171 was undergoing trials nineteen locomotives were ordered to be built to a similar design, of which thirteen were built as 4-4-2s and six as 4-6-0s.[1]

[edit] Preservation

Because no Saints survived into preservation, the Great Western Society at Didcot is currently reverting 4942 Maindy Hall to be 2999 - Lady of Legend.
