Built at Ashford, rebuilder 1889, rebuilt to F1 October 1913 and withdrawn September 1937. James Stirling (1835-1917) was the son of the Rev. Robert Stirling of “Stirling Cycle” fame. James Stirling had previously made a mark for himself as the forward-looking Locomotive Superintendent of the Glasgow & South Western Railway. Like his brother Patrick Stirling on the Great Northern and his nephew Matthew on the Hull & Barnsley he favoured ample domeless boilers and his locomotives were among the most powerful of their day. The SER F class was a class of 4-4-0 steam locomotives of the South Eastern Railway. The class was designed by James Stirling and introduced in 1883. The locomotives passed to the South Eastern and Chatham Railway in 1899 and 76 were rebuilt by Harry Wainwright to Class F1 between 1903 and 1919. On 21 March 1898, F class locomotive No. 205 was hauling a passenger train which was in a rear-end collision with another at St Johns. London due to a signalman’s error. Three people were killed and twenty were injured.
