Clogher Valley Railway 0-4-0 Locomotives in Ireland

Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 5081)

From, a reprint of a 1996 article in the Phoenix by EA Wade talks about the complicated history of this little engine. Initially sold to the Clogher Valley Railway (works # 114), the engine proved unsatisfactory. It was delivered with a boiler offering 60 sq ft of heating surface and a 3.3 sq ft grate area. WA provided the larger boiler shown in the specs in March 1929, but CVR was flatly unhappy with the whole business and put the machine in mothballs, writing off the 950 pound investment.

County Donegal bought the remains (sans boiler, cylinders, brakes, and lighting) and put a diesel powerplant in the vehicle. As modified, the little locomotive dubbed Phoenix operated for decades.
