The GNR(I) Q Class 4-4-0 steam locomotives of the Great Northern Railway (Ireland) (GNR) were mainly used on cross-border mixed traffic duties between Dublin and Belfast, as well as the "Derry Road" between Portadown and Derry. It was designed for the GNR under the auspices of Charles Clifford and built by Neilson, Reid and Company, North British Locomotive Company and Beyer, Peacock and Company. The Q Class is slightly smaller than the GNR class S 4-4-0 [1] but powerful enough to haul a rake of eight or more carriages.
Faster running was achieved with the addition of superheated boilers and widened cylinders (under the supervision of G.T. Glover in the 1920s). In 1932 a two coach special hauled by No. 135 covered Dublin to Drogheda at an average speed of 79.2 mph (127.5 km/h), the fastest run in Ireland up to that time.[2]
Preservation
One member of the Q Class, Number 131,[3] is presently being restored by the Railway Preservation Society of Ireland. It was used mainly on northern routes, the former Ulster Railway main line between Belfast and Clones and the "Derry Road" between Belfast and Derry via Portadown.[4] While in service it was in standard GNR black livery. It worked on Córas Iompair Éireann lines from 1958 and was withdrawn in October 1963.
In the late 1970s the locomotive was repainted and placed on a plinth at Dundalk station. In June 1984 No. 131 and its tender were moved to Mallow, County Cork as the main locomotive of the Great Southern Railway Preservation Society. However, this venture was unfulfilled and the locomotive (partially stripped down and with the boiler and firebox out of the frames) was moved to Inchicore Railway Works in the late 1990s while the running frames were moved to Whitehead, County Antrim in May 2003. The Railway Preservation Society of Ireland bought the locomotive from CIÉ in April 2005.[5]
In November 2013, funding under the Generating Opportunities Within (GROW) South Antrim scheme was allocated, permitting (together with completion of No.171 Slieve Gullion's protracted overhaul) the full restoration of No.131. A return to mainline service in 2015 is currently (Dec 2013) anticipated.[6]
