Rail transport in Ireland is provided by Iarnród Éireann in the Republic of Ireland and by Northern Ireland Railways in Northern Ireland.
The Belfast and County Down Railway (BCDR) was an Irish gauge railway in Ireland linking Belfast with County Down. It was built in the 19th century and absorbed into the Ulster Transport Authority in 1948. All but the line between Belfast and Bangor was closed in the 1950s, although some of it has been restored near Downpatrick by a heritage line, the Downpatrick and County Down Railway.
The Downpatrick and County Down Railway (DCDR) is a 5 foot, 3 inch gauge heritage railway in County Down, Northern Ireland. It is operated by volunteers and runs passenger trains using steam and diesel locomotives, diesel railcars, and vintage carriages. The railway has approximately three miles (4.8 km) of track in a triangular-shaped layout, which connects the town of Downpatrick with the historical sites of Inch Abbey to the north and King Magnus’ Grave to the south. It also houses a museum of railway artefacts and rolling stock originating from both Northern Ireland and the Republic of Ireland, dating from the 1860s to the 1980s.
The Córas Iompair Éireann 611 class locomotives were delivered from the manufacturers, Motorenfabrik Deutz at Cologne, Germany between December 1961 and February 1962, entering revenue earning service in the following August after receiving the new tan / black paint job at Inchicore.
The NIR 101 Class is a class of diesel-electric locomotive formerly operated by Northern Ireland Railways (NIR). With the return to the working of the Enterprise service from Belfast to Dublin with coaching stock instead of augmented diesel railcar sets, NIR found itself with no suitable main line diesel locomotives. The 101 Class (DL) became the answer to the immediate problem working in conjunction with the newly acquired British Rail Mark 2 coaches.
A wide variety of hauled coaches have been used on the railways of Ireland. This page lists all those since 1945.
The Great Northern Railway V class steam locomotives were 4-4-0 three-cylinder compound locomotives built in 1932 by Beyer, Peacock & Company for the Great Northern Railway (Ireland).
The Great Southern Railways Class 800 steam locomotives were built principally for express passenger work on the Dublin to Cork main line of that company. 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 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.
Londonderry Port and Harbour Commissioners (LPHC) No. 3 R H Smyth is a preserved Irish steam locomotive.
The Great Southern and Western Railway Class 90 is a class of 0-6-0T steam locomotive. They were one of the smallest steam locomotives to be inherited by the CIÉ on its formation.
The SLNCR Lough Class was a class of 0-6-4T steam tank locomotives of the Sligo, Leitrim and Northern Counties Railway (SLNCR).
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 but powerful enough to haul a rake of eight or more carriages.
The Dublin and South Eastern Railway 15 and 16 were a pair of 2-6-0 steam locomotives which were built for the heavy goods (freight) traffic on the Dublin to Wexford main line of the Dublin and South Eastern Railway (DSER). The two locomotives were built by Beyer, Peacock and Company at their Gorton Foundry in Manchester.
The Irish Traction Group is a railway preservation society dedicated to preserving diesel locomotives from Irish railways. It was founded on 4 June 1989 with the intention of attempting to preserve at least one example of every type of diesel locomotive to have operated on the Irish Rail system. The ITG's locomotives and work are spread across three sites: Carrick-on-Suir railway station, the Downpatrick and County Down Railway (DCDR), and the West Clare Railway.
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.
The Great Southern Railways Classes 372 and 393 were types of 2-6-0 ("mogul") steam locomotives exported to Ireland from Great Britain in 1924. They were designed by Richard Maunsell in 1914 for the South Eastern and Chatham Railway (SECR) to be members of the SECR N class of mixed-traffic engines. The GSR 372 and 393 classes were part of a batch of N and U class locomotive kits produced under a UK Government contract at the Royal Arsenal, Woolwich.
Tubize 2179 is a preserved Belgian 600 mm narrow gauge steam locomotive built by Ateliers de Tubize as one of six of its class, and used for most of its life in Poland. The wheel notation is 4-6-2 (2C1). It is currently also known as Pacific or Cukrownia Chełmica No.1.
The NZR Y class was a class of three 0-6-0T tank steam locomotives. Built by the Hunslet Engine Company for the Public Works Department in 1923, all three were sold to NZR between 1938 and 1945.
