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

Five were built by Beyer, Peacock and Company in 1915, with an addition five built in 1947, making them the last inside-cylinder 4-4-0 locomotive 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.

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