The 2700 and 2750 Classes are two related types of diesel multiple unit operated by Iarnród Éireann. The 2700 Class units are 2-car sets; 25 cars were built by GEC Alsthom in 1997 and 1998, and began entering service in December 1998. Each car weighs 38 long tons (39 t; 43 short tons) and is fitted with a 350 hp (260 kW) underfloor Cummins engine with a maximum service speed of 110 km/h (68 mph).

From July 2004 to April 2005 they were used in six-piece sets on the Dublin-Rosslare InterCity services, before being replaced by newer units. The entire class was then based in Limerick, with one set outbased in Ballina to operate the Ballina - Manulla Junction shuttle, while it also operated an Athlone - Galway service on Fridays. A further set operated morning and evening Athenry - Galway commuter services during its layover from Limerick - Galway services. Otherwise the class operated all services from Limerick (save direct Limerick-Heuston Station trains) and services from Limerick Junction to Waterford .

They were capable of operation in consists of up to 10 cars, either within their own class or with 2600 Class, 2800 Class, or 29000 Class DMUs. In addition to the 2-car units, two single car units were constructed. These units were classed as 2750 Class, and had a cab at each end so that they could operate either singly or as part of a set.
