Description (1957) |
Churchward 2-cylinder 4-6-0's, wheel diameter 6' 8½", built between 1902 and 1913. Originally a class of 77 engines numbered 2900-2955, 2971-2990 and 2998. Nos. 2971/2, 2979-2990 were constructed as 'Atlantics' and later converted to 4-6-0's. Successive batches were named after 'Ladies', 'Saints', 'Courts', and sundry names associated with Sir Walter Scott's novels, but the whole class was generally known as 'Saints'. No. 2925 Saint Martin was rebuilt in 1924 with 6' 0" wheels and renumbered 4900, becoming the prototype of the 'Hall' class. Scrapping commenced in 1931 and the last survivor, No. 2920 Saint David, was withdrawn in 1953. |
