Rail Services in Ireland are provided by Iarnród Éireann in the Republic of Ireland and by Northern Ireland Railways in Northern Ireland. Most routes in the Republic of Ireland radiate from Dublin. Northern Ireland has suburban routes from Belfast and two main InterCity lines from same, one to Derry and cross-border to Dublin Connolly.

Ireland's only light rail service is in Dublin and is a tram service called Luas. No Metro lines currently exist in Ireland but a Dublin Metro, Meitreo Átha Cliath, is planned.

HistoryEdit

The first railway in Ireland opened in 1834. At its peak in 1920, Ireland had Template:Convert of railway, now only about one third of this remains. A large area around the border area has no rail service.

Ireland's first Light rail line was opened in 30 June 2004.

TractionEdit

LocomotivesEdit

Main article: Diesel locomotives of Ireland

Diesel traction is the sole form of motive power in both the IÉ and NIR networks, apart from the electrified Howth/Malahide-Greystones (DART) suburban route in Dublin. Apart from prototypes and a small number of shunting locomotives, the first major dieselisation programme in CIÉ commenced in the early 1950s with orders for ninety-four locomotives of two sizes (A and C classes) from Metropolitan-Vickers which were delivered from 1955, with a further twelve (B class) locomotives from Sulzer in the late 1950s.

Following poor reliability experience with the first generation diesel locomotives, in the 1960s a second dieselisation programme was undertaken with the introduction of sixty-four locomotives in three classes (121, 141 and 181) built by General Motors, of the United States. This programme, together with line closures, enabled CIÉ to re-eliminate steam traction in 1963, having previously done so on the CIÉ network prior to taking over its share of the Great Northern Railway. In parallel, NIR acquired three locomotives from Hunslet, of England, for Dublin-Belfast services. The Metropolitan-Vickers locomotives were re-engined by CIÉ in the early 1970s with General Motors engines.

The third generation of diesel traction in Ireland was the acquisition of eighteen locomotives from General Motors of 2475 h.p. output, designated the 071 class, in 1976. This marked a significant improvement in the traction power available to CIÉ and enabled the acceleration of express passenger services. NIR subsequently purchased three similar locomotives for Dublin-Belfast services, which was the first alignment of traction policies by CIÉ and NIR.

A fourth generation of diesels took the form of thirty-four locomotives, again from General Motors, which arrived in the early 1990s. This was a joint order by IÉ and NIR, with thirty-two locos for the former and two for the latter. They were again supplied by General Motors Electro-Motive Division. IÉ designated their locomotives the GM 201 class; numbered 201 to 234 (the NIR locos were later prefixed with an 8). These locomotives are the most powerful diesels to run in Ireland, and are of 3200 horsepower (2.5 MW), which enabled further acceleration of express services. The NIR locos, although shipped in NIR livery, were repainted in 'Enterprise' livery, as were two of the IÉ locos.

The 071 class are now used on freight services. NIR's three similar locomotives are numbered 8111, 8112 and 8113. There is seldom more than one of these serviceable at a time. NIR regularly lends these locomotives to IE.
