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.

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 14th and 15th November 075 and a Tara Mines train was used in testing of the new bridge at Malahide.
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 used for ballasting duties, as well as hauling the old "Gatwick Express" carriages. These locomotives are numbered 111, 112, and 8113. It is envisaged that all will be withdrawn from passenger services along with the rest of NIR's life expired rolling stock once the planned "New Trains 2010" units enter service. [1] In 2007, it was announced that NIR's three locomotives were to be converted to push-pull operation.[2] 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. In addition to their passenger duties, the locomotives are primarily used for permanent way or shunting.
Recently locomotive 111 was renumbered 8111 and it’s likely that 112 will be renumbered 8112.

| 8111 | Great Northern |
| 112 | Northern Counties |

The 071 Class is currently available as a 00 gauge Resin kit by Model Irish Railways (MIR). It includes transfers, brass detailing (railings, fans, grills) and flush glazing. Note that the paint included is the Golden Brown hue and not the existing deep orange (RAL2011).[3]
Murphy Models have announced plans to release an '00' gauge ready to run model of the 071 class.[4]
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.[5]
Four similar EMD JT22CW-2 locomotives are used by Serbian Railways, designated as ŽS series 666. They were originally intended 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 1600mm gauge and having a full width car-body.[5]
