Data from "Ten-Wheeled Tank Engines", Railway Engineer, Volume 20, No 1 (January 1899), pp. 10-13; and "Locomotives for the Waterford, Limerick and Western Railway", Engineer, Volume 84 (13 August 1897), p 154.
Engineeri reported that this class was of the "Blarney Castle class", which was also the name for the 21. The others were Rocklands, Faugh-a-Ballagh, and Geraldine. The wheel arrangement consisted of a four-wheel bogie, four wheels coupled, and a trailing radial truck. The cylinders, drivers, boiler, and firebox repeated the dimensions of the slightly earlier 0-4-4Ts described in Locobase 20249.
Locomotive superintendent John G Robinson intended this class to work the Limerick to Collooney line's northern section to Tralee (70 miles/ 113 km) as well as the Sligo and Kelly lines, which featured many gentle curves. Their coal consumption averaged 18 lb/mile (5.07 kg/km).
In January 1901, the Great Southern & Western acquired both the WL&W and the Waterford & Central Ireland.
Almost 30 years later, the class received slightly larger boilers in 1925-1926 that contained 894 sq ft (83.06 sq m) of evaporative heating surface area and 15.8 sq ft (1.47 sq m) of grate area.
Retirements came in 1949 and 1957.
