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 a EMD 12-710G3B engine of 3200 hp, weigh 112 tonnes and have a maximum speed of 164 km/h (102mph).

Regional Allocations

Numbers 206-209 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)). Because of the shared nature of these services, 208 and 209 are owned by Northern Ireland Railways. This explains the different naming arrangements for these two locomotives. Enterprise services require electrical power to be supplied from the locomotive - head end power - and the engines are frequently swapped to non-Enterprise services to prevent permanent damage from prolonged operation in this mode. In order to prevent wear on the original locomotives, two further units (230 ''Abhainn na Bandan'' and 233 ''Abhainn na Chlair'') have been allocated to Enterprise.
The entire class is named after Irish rivers, with the IE locomotives carrying two nameplates, one in Irish and one in English, on each side of the locomotive. 208 and 209 carry only English language nameplates.
Push-pull equipped members of the 201 class are being repainted in a new livery of Fern Green
(NCS 4550-G), Grey (RAL 7000), Yellow (RAL 1021), Black (RAL 9005), Green (NCS 7020- B70G), Yellow Green (NCS 1070 G60Y) & Silver (761) to coincide with the deployment of new MK4 carriages.

Model

In 2001, Murphy Models commissioned LIMA to produce an '00' gauge model of these locomotives [5]. They were produced in IE (201,216,217,219,230), Enterprise (206,207,208) and NIR (208,209)liveries, all in batches of 300 (the exception being 500 of #207).
