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 trains) and services from
Limerick Junction to
Waterford. They were capable of operation in consists of up to 10 cars. 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. Even numbered cars had 62 seats while odd numbered cars contained 55 seats and a toilet. There were some exceptions however; the two 2750 Class units had 53 seats each, due to having cabs at both ends, while 2719 and 2721 had 50 seats each and included a bicycle storage area. The original black and orange
Arrow livery was replaced by the newly introduced Commuter livery in 2004, upon the start of the sectorisation of Iarnród Éireann's operations. In 2010, Iarnród Éireann began major overhauls of the 2700 and 2750 Classes, the most prominent feature of which was the removal of the end
gangways, which had been unused for some time. This coincided with the addition of a new livery based on the
22000 Class colour scheme. 2716 suffered collision damage on 3 June 2000. Following repairs, it was coupled with 2609, part of the
2600 class. In July 2012, the majority of the class was withdrawn and put into storage; by September 2012 the entire fleet had been withdrawn and was put up for sale. As of 2018, the entire 2700 fleet remains decommissioned at
Inchicore Works in
Dublin and in the sheds at
Cork Kent. Irish Rail announced in 2016 that the 2700s were to be reintroduced into service around Limerick from 2018 to free up 22000 Class sets. In October 2017, Irish Rail put out to tender the reactivation and refurbishment of 10 2700 sets, which were due to re-enter service in early 2019 in order to free up ICR sets for busier Dublin area services. However, this plan was cancelled in 2018. During 2022, the 2700s stored at Inchicore were removed from the rails and stored off-track to make more space for other rolling stock. Irish Rail would approve the scrapping of the fleet in August 2023. Scrapping of the fleet commenced in Inchicore in March 2025, with the units stored in Cork being hauled to Inchicore in April. Carriages were cut up and sent to
Louth for scrapping. ==Preservation==
