See also R M Livesey, "Rolling-Stock on the Principal Irish Narrow-Gauge Railways", Engineering, Volume 94, (2 August 1912), pp. 169-176, table on p. 175. Works numbers were 3369-3374.
The Clogher Valley was incorporated on 26 May 1884 and opened three years later. It offered 37 track miles (60 km) in County Tyrone between Tynan and Maguiresbridge, both of which had stations on the GNR. Never a big money-maker, the line closed 31 December 1941.
Principal power on the CVR were these six tanks delivered in 1886-1887 After Caledon came Errigal, Blackwater, Fury, Colebrooke, and Erne. The cylinders were inclined on a 1 in 15 angle, possibly to clear the front driving axle. All of the running gear was sheathed by plates suspended from the running board to protect nearby human and animal traffic. The class was rated at 70 tons maximum load on the road's ruling gradient.
Fury was scrapped first in 1929, Colebrooke in 1936 and the other four after the line closed.
