Ceylon Government Railway 4-4-0 Locomotives in Ceylon
Class Details by Steve Llanso of Sweat House Media
Class F2 (Locobase 6369)
Data from [
] (a page of the ca. 1920 Vulcan Foundry catalogue). See also Eng. Udaya Peeligama, "A Concise History Of Motive Power Development On Sri Lankan Railways", presented on the Institution of Engineers Sri Lanka-New South Wales Chapter website at [
], posted 7 September 2018, last accessed 3 August 2021. Vulcan Foundry delivered five engines--works number 2629-2631 in 1911 and 2890-2891 in 1913. North British Locomotive Company supplied 15 in 1911-1913.
(Note: 144-151 delivered as 152-154, 157-161, then renumbered).
The photograph shows a rather stubby profile with Belpaire firebox, capped stack. Eng. Peeligama noted the relatively modern qualities of these Eight-wheelers and added that they "lasted well into the final days of steam in the late 1960s.
Class F3 (Locobase 13590)
Data from Charles Rous-Martens, "British Locomotives for Abroad", Page's Magazine, Volume III, No 1 (July 1903), p. 117. Dubs & Company produced 6, Kitson 2, and North Brtish Locomotive Company 4 in 1900-1903.
