Editing CIÉ 611 Class (section)

==History==
Nos. 611 to 617 were a larger development of the earlier [[CIÉ 601 Class|601 class]] locomotives. They were fitted with a Deutz F/A8L 714 engine of {{convert|120|kW|hp}}, with Voith hydraulic transmission, weighed {{convert|22|t}} and had a maximum speed of {{convert|42|km/h|mph}}.
They went into traffic in various parts of the country, as shunting engines at smaller depots such as [[Dublin]]'s North City Mills siding and branch line duties such as the [[Loughrea branch line]] between [[Attymon]] and [[Loughrea]]. They briefly appeared on the [[Limerick–Foynes railway line|Limerick - Foynes]] mixed train service for a few months until that line was closed in 1963. Unlike the earlier 601 class, these locomotives were fitted with brake connections enabling them to work passenger trains. Apart from their use on the Foynes and Loughrea lines, they never hauled passengers until preservation in Downpatrick, where all three preserved have served on public passenger trains.

With their original lightweight branch line haunts all closed and therefore little to do, they were withdrawn from service between 1967 and 1977. Nos. 611, 613, 615, 616 and 617 were sold to Cómhlucht Siúicre Éireann (Irish Sugar Co., now known as [[Greencore]]) in 1977. Four of these locomotives have been preserved, with the remainder scrapped.
