The Great Northern Railway (Ireland) class S was a class of five 4-4-0 steam locomotive that the Great Northern Railway introduced in 1913 to haul Belfast – Dublin express passenger trains. They were followed two years later by the three similar class S2 locomotives.

All were built by Beyer, Peacock and Company at their Gorton Foundry, Manchester.

Names[edit]

The locomotives were delivered during a time when the GNRI was removing names from locomotives. The S class locomotives carried names from new, but gradually lost them, so by 1925, only 170 Errigal retained its name. This it lost in 1930.[2] The S2 locomotives were allocated the names Lugnaquilla, Carlingford, and Mount Hamilton, but they were never carried. With the introduction the class V locomotives in 1932, the GNRI revived the practice of naming locomotives; the S2 class acquired new names, and the S class regained their old ones as they went though the works for rebuilding in the late 1930s. All were named after mountains in Ireland.

1958 dispersal[edit]

Much of the GNR network was closed in 1957 and the remaining system was split between Córas Iompair Éireann (CIÉ) and the Ulster Transport Authority (UTA) in 1958, with the fleet divided as equally as possible between the two parties. The UTA renumbered their locomotives, whereas the CIÉ merely added an "N" suffix to the locomotives' former GNRI numbers.

CIÉ soon replaced its remaining steam locomotives with diesels and sold four of its former GNRI steam locomotives – all three S class and one VS class – to the UTA in 1963.[3]

The UTA based some of its S class locomotives in Belfast and used it to haul trains on the Belfast – Portadown main line and Portadown – Derry "Derry Road".

Preservation[edit]

One member of the class, No. 171 Slieve Gullion, is preserved.[4] In preservation it has covered most of the Irish railway system, including many non-GNR(I) lines.

171 is currently[when?] stored at the Railway Preservation Society of Ireland's centre at Whitehead, County Antrim. 171 was operational until 2002 when it was withdrawn for a boiler overhaul. It will begin to be restored with a view to returning to service for the RPSI's 50th anniversary in 2014, and a fundraising appeal has been launched to raise the funds needed for its restoration.[5]

In November 2013, funding to complete the overhaul of No.171 was allocated under the Growing Rural Opportunities Within (GROW) South Antrim scheme. The contract to restore this locomotive (within a 9 month timeframe) has (Dec 2013) gone out to tender.[6]

Model[edit]

The S Class is currently available as a 00 gauge etched-brass kit from Studio Scale Models. It includes transfers, brass etches and cast white metal parts.
