Cie 071 Class




The Córas Iompair Éireann 071 Class, and the identical Northern Ireland Railways '''111 Class''', Locomotive s were the principal passenger locomotives on the Irish railway network for twenty years from their introduction in the late 1970s. They displaced the older CIE 001 Class and NIR 101 Class locomotives from these duties, which included the ''Enterprise'' service between Dublin and Belfast , and were themselves replaced by the new 201 Class locomotives.

All the CIE locomotives remain in service, but now working second-tier passenger duties, and have been joined by NIR 112, which is on long term loan from NIR since April 2003. Of the other NIR locomotives, 111 & 113 (now renumbered 8113) are currently out of service.
