RTÉ’s Big Music Week was run in association with Iarnród Éireann, which provided a three carriage ICR train for the musicians and their guests. The 22000 Class “InterCity Railcar” is a diesel multiple unit usually used on commuter routes such as Kildare, Portlaoise and Longford to Dublin and on Irish Rail’s intercity routes except Dublin to Belfast (served by the Enterprise) and peak-time journeys from Dublin to Cork. There are 48 of them and they can seat 190 passengers. They are capable of speeds up to 160 km/h (100 mph).
The sets were supplied by Mitsui of Japan in an order totalling approximately €400 million. The fleet was built by a partnership between Hyundai Rotem of South Korea and Tokyu Car Corporation of Japan, who supplied the bogies. The first sets were delivered in March 2007. Two of the 3-car sets, 22010 and 22011, which arrived in July 2007, suffered corrosion damage in transit from South Korea. They were returned to Rotem for repair in October 2008, with a revised delivery date. It was later determined that it was uneconomic to repair them and two replacement units with the same numbers were provided at no cost to Iarnród Éireann.
The ICRs are divided into three car sets and six car sets, and have two internal configurations. The first 30 units are all three cars, and are all intended for use on Intercity routes, as are ten of the 15 six car units. The remaining five 6-car sets, plus the 17 three car sets ordered in 2008 are configured for long-range commuter services to and from Dublin. Combinations of two 3-car sets, three 3-car sets, two 6-car sets and a 3-car set + a 6-car set are possible. In case of emergency, they can operate in formations of up to 18 cars.
