The [[Córas Iompair Éireann]] '''113 class''' [[locomotive]]s were the first mainline diesel locomotives used in Ireland, being built in January 1950 and October 1951 by CIÉ at their [[Inchicore railway works|Inchicore Works]]. They were fitted with [[Sulzer (manufacturer)|Sulzer]] 6LDA28 engines of {{convert|915|hp|abbr=on}} (uprated to {{convert|960|hp|abbr=on|disp=or}} in 1956), with four [[Metropolitan-Vickers]] MV157 traction motors. They were of Bo-Bo [[UIC classification|wheel arrangement]], weighed 80 tonnes and had a maximum speed of {{convert|90|km/h|abbr=on}}. They were initially numbered 1100–1101 in the steam locomotive number series (and designated class C2a), but were subsequently renumbered B113–B114 in 1957.

==History==
They were intended for mixed traffic duties, hauling both freight and passenger trains. When they were first introduced, they were used on some of the express passenger duties between [[Dublin]] and [[Cork (city)|Cork]]. However, with the arrival of production diesel locomotives (the [[CIÉ 001 Class|001]] and [[CIÉ 101 Class|101]] Classes) from 1955, these two locomotives were used more for freight work, mostly in the area around Dublin.

They suffered from a recurring brake fault and following a serious incident in August 1971 when 114 ran away while working a goods train, both locomotives were withdrawn for modifications to be made to their brakes. In fact, 114 was never reinstated and 113 only worked for a few months at the end of 1974 before it too was stored again. Both were then used at Inchicore Works as part of a sound barrier with 101 Class locomotives. B113 was presented to the [[Ulster Folk and Transport Museum]] in May 2011, but 114 was scrapped in March 1995.<ref>{{cite web|url=http://www.derbysulzers.com/cie.html|title=CIE 113 - 114 (1100 - 1101)|website=derbysulzers|date=2004-05-12|access-date=2006-03-24}}</ref>

==Preservation==
[[File:Cultra 1.jpg|thumb|left|B113 On display at the UFTM]]
B113 was preserved by [[Iarnród Éireann]] at Inchicore works, Dublin, and received a cosmetic restoration there. It was then transferred to the RPSI's depot in [[Whitehead, County Antrim]] and later taken to the Ulster Folk and Transport Museum for static display in January 2012, along with [[NIR 101 Class]] No. 102. The two locos are currently incapable of running under their own power, and so [[CIÉ 071 Class#Northern Ireland Railways|NIR 111 class]] locomotives 112 and 113 provided motive power for the move.
