The Dublin, Wicklow and Wexford Railway(Later named the Dublin and South Eastern Railway and a new livery in 1907) was approached by the London and North Western Railway who were selling six 4ft 6in Tank Engines in 1902, the DWWR agreed on the sale and the LNWR converted the engines to 5ft 3in Gauge at Crewe. Originally the engines had been built at Crewe as 2-4-0T in 1877 but converted to 2-4-2T in 1896. When the engines arrived they were the only engines to have Allan's Straight Link Valve Gear however drivers were not happy with them saying the old single tank engines were better. The engines were based at Bray and worked on the Harcourt Line. By 1913, five of the six engines were being stored a Bray as they weren't getting used and so five were sold in 1916 to British Companies who were lacking motive power due to WW1. No.60 and No.62 were sold to the Inland Waterways and Docks Co at Richborough Port as No.42 and No.43 surviving until 1919. No.63 went to the War Department at Shoeburyness Garrison as No.12 WD4190 but still retained its DWWR/DSER name Earl of Carysfort. No.59 and No.61 were sold to J F Wake of Darlington who had them converted from Irish Gauge at his own works however they were late sold to the Cramlington Coal Company becoming their No.13 and No.14 surviving till 1923 and 1929. The remaining DSER XXV was No.64 who was rebuilt at Grand Canal Street Dublin in 1914 and was used as the second train for Carlisle Pier. Includes AJS Script.
