The Córas Iompair Éireann 071 Class or Northern Ireland Railways 111 Class is a General Motors Electro-Motive Division EMD JT22CW series diesel-electric locomotive used in both the Republic of Ireland and Northern Ireland.
Serbia utilises four similar locomotives as JŽ series 666.
Córas Iompair Éireann
The Córas Iompair Éireann 071 Class locomotives were the principal passenger locomotives on the Irish railway network for twenty years from their introduction in the late 1970s. They displaced the older CIÉ 001 Class and NIR 101 Class locomotives and were themselves replaced in turn by the new 201 Class locomotives.
Currently all the CIÉ locomotives remain in service, but are used on freight and permanent way trains. NIR 112 was on long term loan to Iarnród Éireann from April 2003 until September 2006 but has since returned to Northern Ireland Railways.
As of late 2006, IÉ began an overhaul programme of twelve units only, leaving the fate of their remaining six units in doubt. To date fourteen 071s have received the new 'Freight Livery’ however not all have received an overhaul. Those that have received a re-paint into the new livery are: Nos. 071, 072, 073, 074, 075, 076, 079, 080, 081, 082, 083, 085, 086 and 088.
On 14 and 15 November 2009 075 and a Tara Mines train was used in testing of the new bridge at Malahide.
In 2013 an overhaul programme started for all eighteen class members which includes an engine rebuild, refurbished bogies, new panels, new cabs and a new slate grey livery complete with European numbering. As of May 2015 locos 071, 077, 078, 084, 085, 087, 088 have been refurbished with 076 being overhauled as of May 2015. Class members that had been out of use for a number of years have been reinstated into service after overhaul.
Northern Ireland Railways
The Class 111 as they are known by NI Railways is identical to the Class 071. NI Railways has three of these locomotives, which are now mainly used for ballasting duties since their replacement on the Enterprise and other passenger duties. These locomotives are numbered 8111, 112, and 8113.
In 2007, it was announced that NIR's three locomotives were to be converted to push-pull operation. The DBSO driving trailer for this set was due to be delivered in 2009, leading to speculation that this set may remain in service after 2010, and may even see increased use in passenger service.
As of 2015 the DBSO has been disposed of, never having been used, and is now preserved at Downpatrick and used as a barrier vehicle for their Class 450 DEMU. The Gatwick Express carriages have also been disposed of to the RPSI, leaving the Class 111 locomotives with no normal passenger duties. They remain in use for permanent way & engineering duties, and very occasional stock movements for the RPSI.
Yugoslavia and Serbia
Four similar EMD JT22CW-2 locomotives are used by Serbian Railways, designated as ŽS series 666. They were originally intended by Yugoslav Railways for use with Tito's special Blue Train, hence their all blue livery. These locomotives differ from the Irish units in being standard gauge rather than Irish 1600mm gauge and having a full width car-body. After dissolution of Yugoslavia, locomotives have been used to haul freight and passenger trains. Three locomotives are currently not operational and awaiting overhaul, while the 003 (Sutjeska) started running test rides in January 2015 after the overhaul in Kraljevo. On January 23, 2015 the 003 has reentered to service.

Accidents and incidents
- On 1 August 1980, locomotive 075 was hauling a passenger train which was derailed at Buttevant, County Cork, killing eighteen and injuring 62 people.
- On 21 August 1983, locomotive 086 was hauling a passenger train which ran into the back of a passenger train near Cherryville Junction, County Kildare. Seven people were killed and 55 were injured.
The 071 Class was available as a 00 gauge Resin kit by Model Irish Railways (MIR) but is no longer made. It included transfers, brass detailing (railings, fans, grills) and flush glazing. Note the paint included is the Golden Brown hue and not the existing deep orange (RAL2011).
Murphy Models have released an '00' gauge ready to run model of the 071 class. This has been available since October 2012.
Both the 071 and 111 class have been produced as player drivable locomotives in the Microsoft Train Simulator add-on, "Irish Enterprise North" by Making Tracks.
