The Iarnród Éireann (IE) 201 Class locomotives are the newest and most powerful diesel locomotives operating in Ireland, and were built between 1994 and 1995 by General Motors. They are model type JT42HCW, fitted with an EMD 12-710G3B engine of 3,200 hp (2,400 kW), weigh 108.862 tonnes (107.143 long tons; 120.000 short tons) and have a maximum speed of 164 km/h (102 mph). A freight version, the EMD Series 66, with the same engine is used on privately operated European mainline freight duties.
By the early 1990s, the locomotives operating passenger services in Ireland were becoming increasingly obsolete, with the newest type in service being the 071 Class introduced in 1976. The economic boom in Ireland in the mid-1990s allowed Iarnród Éireann to begin significant investment in the infrastructure of the railways, which began with an order for 32 brand new express locomotives from GM-EMD. Northern Ireland Railways also purchased 2. The first were delivered in 1994, with deliveries continuing until 1995.
To allow clearance tests and driver training to commence in advance of the delivery of the main order of 201s, it was decided to transport the first locomotive, number 201, to Dublin by air. An Antonov An-124 was used to transport the locomotive from London, Ontario to Dublin Airport, arriving on 9 June 1994. The first light-engine test run operated from Inchicore works to Kildare on the 14th.
Unfortunately, the locomotives have had a chequered service history. The authors of Jane's Train Recognition Guide noted that IÉ had had problems with engine fires and bogie cracks.

|206-209, 227, 228, 230, 231, 233||Enterprise||208-209 owned by NIR; others owned by IÉ. 230 remains out of service after fire in 2013.|
* NPP = Non Push-Pull Capable; PP = Push-Pull Capable
InterCity operated, push-pull equipped members of the 201 class were repainted in a new livery of Fern Green to coincide with the deployment of new Mark 4 carriages which were rolled out during 2006-2007 to serve on the Dublin-Cork line. Apart from the Enterprise Dublin-Belfast line, This is the only in Ireland were locomotive hauled coaches are in use. All locomotives have full yellow ends to improve visibility.
Numbers 206, 207, 8208, 8209, 227, 228, 230, 231 & 233 are dedicated for use on the Enterprise passenger service between Dublin and Belfast, and are painted in a special livery of (Dark Grey (NCS 8502-Y), Light Grey (NCS 5502-Y), Dark Green (NCS 9005-G20Y), Purple (NCS 5040-R40B) & Bronze stripe (3M 180-229)). All locomotives have full yellow ends to improve visibility.
Because of the shared nature of these services, 8208 and 8209 are owned by Northern Ireland Railways. This explains the different naming arrangements for these two locomotives. Until September 2012, Enterprise services required electrical power to be supplied from the locomotive - head end power, when four Mark 3 generator vans entered service.
List of locomotive names
The entire class is named after Irish rivers, with the IÉ locomotives carrying two nameplates, one in Irish and one in English, on each side of the locomotive. As 8208 and 8209 are owned by Northern Ireland Railways, they carry English language only nameplates. The nameplates are trapezium shaped, with the names in upper case.

All of the non push-pull capable locomotives (201–205 and 210–214) were placed in storage at Inchicore during 2009, the last being 214 in July 2009. This is due to the withdrawal of the Mark 3 fleet and replacement with 22000 Class railcars on the vast majority of passenger services. This left only the Mark 4 Dublin–Cork services and the cross-border Enterprise service (with De Dietrich rolling stock) as the only locomotive hauled passenger services operated by Iarnród Éireann. The reduction in the number of locomotive hauled passenger workings, combined with the withdrawal of older GM locomotives, has seen Class 201 locomotives used on freight workings, whilst four push-pull capable units were transferred to join the original four dedicate locomotives in use on the Enterprise. In 2010 Iarnród Éireann planned to store some of its remaining push-pull capable Mark 3 coaches, which could potentially have been used with 201 Class locomotives to enhance Enterprise's service. However, all Mark 3 carriages were scrapped during 2013 and 2014.
In 2001, Murphy Models commissioned LIMA to produce an '00' gauge model of these locomotives. They were produced in IÉ orange (201, 216, 217, 219, 230) and Enterprise (206, 207, 208, 209) liveries, all in batches of 300 (the exception being 500 of #207).
In October 2010 at the Model Railway Society of Ireland Model Railway Exhibition, Murphy Models announced plans to produce their own version of the class 201 to an all new tooling, complete with a sample model for production in the next year.
Model Irish Railways produce a resin body shell kit that includes nameplates, numbering, brass grills and the standard yellow / black livery line transfers.
Marks Models also released a resin kit for these locomotives in 00 gauge around the year 2000.
There is also speculation that Hornby, who now own the moulds for these models, may make a full production run of these models. This would be a first, as they have never made an Irish loco for the mainstream market before.
The 201 class has also been released in virtual form as a player driveable locomotive in the Microsoft Train Simulator add-on, "Irish Enterprise North", by Making Tracks, and for OpenBVE by Celtic Trainsim.
