The GNR(I) class U was a class of 4-4-0 steam locomotives built for the Great Northern Railway (Ireland).

Contents

History

Five were built by Beyer, Peacock and Company in 1915. The class was so successful that an additional batch of five was built in 1947, making them the last inside-cylinder 4-4-0 locomotives to be manufactured anywhere in the world. [1]

The earlier locomotives were initially unnamed. However, after the later locomotives were delivered with names of counties along the GNR(I) route, the earlier locomotives received names of Loughs.

Withdrawal

All were still in service in 1958 when the GNR(I) was divided between the Ulster Transport Authority (UTA) and Córas Iompair Éireann (CIÉ), with each receiving five locomotives.

No. 198 Lough Swilly was the first to be withdrawn in 1959 before its CIÉ number (198N) was applied. CIÉ withdrew steam traction in 1963, whereas the UTA withdrew their U class fleet between 1961 and 1965. None of the class were preserved.

Oliver Vaughan Snell Bulleid CBE was a British railway and mechanical engineer best known as the Chief Mechanical Engineer (CME) of the Southern Railway between 1937 and the 1948 nationalisation, developing many well-known locomotives.

The Córas Iompair Éireann 601 Class locomotives were built in 1956-1957, by Motorenfabrik Deutz at Cologne, Germany. They were 3 small shunting locomotives of B wheel arrangement and were fitted with a Deutz V8 F8L 614 engine of 130 hp, with Voith hydraulic transmission and chain final drive. They weighed only 18 tons and had a maximum speed of 32 kilometres per hour (20 mph). These locomotives were never fitted with train brakes, so had limited usefulness compared to their successors, the G611 class. The G601 locomotives were withdrawn from service between 1965 and 1972.

The Córas Iompair Éireann 101 Class locomotives, numbered B101-B112, were built in 1956 by the Birmingham Railway Carriage and Wagon Company. They were fitted with Sulzer 6LDA28 engines of 960 hp (720 kW), with four Metropolitan-Vickers MV137 traction motors. They were of A1A-A1A wheel arrangement, weighed 75 tonnes and had a maximum speed of 120 km/h (75 mph).

A wide variety of steam locomotives have been used on Ireland's railways. This page lists most if not all those that have been used in the Republic of Ireland and Northern Ireland. Irish railways generally followed British practice in locomotive design.

These locomotives were designed under the supervision of E. C. Bredin with his Chief Draughtsman, H. J. A. Beaumont, preparing the drawings. They were the largest and most powerful engines ever to run in Ireland by quite a large margin, and the only three express passenger locomotives to be built in an independent Ireland.

The Great Northern Railway (Ireland) (GNR(I) or GNRI) was an Irish gauge (1,600 mm (5 ft 3 in)) railway company in Ireland. It was formed in 1876 by a merger of the Irish North Western Railway (INW), Northern Railway of Ireland, and Ulster Railway. The governments of Ireland and Northern Ireland jointly nationalised the company in 1953, and the company was liquidated in 1958: assets were split on national lines between the Ulster Transport Authority and Córas Iompair Éireann.

The GS&WR Class 2 was a lightweight 4-4-0 steam locomotive used by the Great Southern and Western Railway in Ireland in the late 19th and in the first half of the 20th century. They were the first locomotives of type 4-4-0 in Ireland.

The Railway Preservation Society of Ireland (RPSI) is a railway preservation group founded in 1964 and operating throughout Ireland. Mainline steam train railtours are operated from Dublin, while short train rides are operated up and down the platform at Whitehead, County Antrim, and as of 2023, the group sometimes operates mainline trains in Northern Ireland using hired-in NIR diesel trains from Belfast. The RPSI has bases in Dublin and Whitehead, with the latter having a museum. The society owns heritage wagons, carriages, steam engines, diesel locomotives and metal-bodied carriages suitable for mainline use.

The Great Northern Railway (Ireland) T2 class was a class of 4-4-2T tank locomotives. The GNR(I) had introduced the T class numbered 185–189 in 1913.

They proved so successful that a further twenty were commissioned in 1921, 1924 and 1929. Although externally identical in appearance to the T, they were classified as the T2 class having larger tanks and higher boiler pressure, and were used successfully on both fast passenger work and freight.
