The CIE 141 Class locomotives were built in 1962 by General Motors Electro Motive Division (EMD) in the United States. Numbered B141 to B177, they were an updated version of the 121 Class locomotives, mechanically very similar but with cabs at each end. They are EMD model JL8 (J = Double Ended Cabs, L = Lightweight Frame, 8= 8-cylinder 567 engine) and although originally fitted with an EMD 8-567CR engine of , all were later fitted with 645 type "power packs" (piston & liner assemblies) for parts standardisation. The original power output was kept for reliability reasons. They weighed 67 tonnes and had a maximum speed of . Many of these locomotives were later rebuilt with a GM 8-645E engine of (as used in the re-engined Class C locomotives), though some have since had the original engine refitted. The locomotives were delivered in the CIE livery of brown/black/white. Service Following crew training trials between Inchicore and Monasterevin (passenger trains), Kildare (goods trains), and Hazelhatch (light engines), the class appeared on main line trials from Amiens Street (Connolly) to Drogheda, and Westland Row (Pearse) to Arklow on Tuesday 4 December 1962, entering traffic on the Dublin to Cork main line four days later. The locomotives were fitted for multiple working and double-headed the 10:40 Dublin to Cork train and the return Cork to Dublin at 15:30. These were the heaviest trains at that time. From Monday 10 December 1962 one locomotive was allocated to the Dublin–Belfast Enterprise service. In later years, regular passenger duties included trains on the Rosslare to Waterford/Limerick lines, until they were superseded by railcars on these duties. The remaining locomotives, nos. B141, B142, 144, 146, 147, 152, 162, 171, 175 and 177, were withdrawn in February 2010. However, 171 was reinstated for a short time, and was confined to pilot duties in the Dublin area. Accidents and incidents On Tuesday 13 August 1974, locomotive B176 was hauling a passenger train when it was involved in a head-on collision with locomotive B192, which was also hauling a passenger train, at . Fifteen people were injured. On Friday 5 May 1995, locomotive 165 left Cork Kent railway station at roughly 06:30, ferrying an empty train into Cobh. The train failed to stop and continued through the wall of the adjacent Cobh Heritage Centre. There were no injuries incurred by any of the four personnel on board, the driver narrowly
