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.
