West Clare 2-6-2 Locomotives in Ireland
Class Details by Steve Llanso of Sweat House Media
Class Lisdoonvarna (Locobase 2769)
Data from [
] (August 2002) for data. See also "Irish Light Railway Locomotives", Railway Engineer, Volume 21, No..1 (January 1900), pp. 10-12.
Prairie tanks bought over a period of seven years. Lisdoonvarna -- which used the same boiler design as the earlier Slieve Callan -- came first in 1894 from Dubs & Co (works #3169). T. Green delivered the other three -- Fergus in 1898 (#229), Ennis in 1900 (234), and Liscannor (236) in 1901.
They were scrapped over a wider range of years. Lisdoonvarna went in 1922, Liscannor in 1928, Fergus in 1954, and Ennis in 1955.
