The 22000 Class "InterCity Railcar" is a diesel multiple unit in service with Iarnród Éireann in Ireland. They are the first IÉ DMUs built specifically for InterCity routes, although they can also work on some commuter routes. They are designed to operate at a maximum speed of History In 2005, the Irish Government announced the €34 billion Transport 21 proposal for significant improvements to transport infrastructure, with major emphasis on the railway network. As part of this, large-scale replacement of rolling stock was planned, then made up entirely of locomotive-hauled coaching stock, the most based on the British Rail Mark 2 and Mark 3. IÉ ordered 120 replacement vehicles: in a major departure, the new trains would be 3 and 6 car DMUs rather than locomotive-hauled carriages. This order was extended to 150 vehicles in 2005, to 183 vehicles in 2007 and to 234 vehicles in December 2008. 41 additional centre cars were ordered in 2019 for delivery from 2021. No new driving cars would be ordered but as many services operate with two units joined currently it would be possible to reconfigure and release more units. All units are underwent an in-service interior overhaul between 2019 and 2022. This programme included replacing the original cloth seats with leather and adding USB power sockets at each seating bay, amongst other changes intended to reduce ongoing maintenance and cleaning costs. Deliveries Supplied by Mitsui of Japan for approximately €400 million, the fleet was built by a partnership between Rotem of South Korea and Tokyu Car Corporation of Japan, who supplied the bogies. The first sets were delivered in March 2007, while the final sets were delivered in April 2012. In March 2007, a €79 million order was placed for a further 33 vehicles to be used primarily on the outer Dublin commuter network. This was added to with an additional 51 Commuter vehicles in December 2008. As of 2015, there are 63 sets: 28 3-car sets, 25 4-car sets and 10 5-car sets, in three different layouts. Two of the 3-car sets, 22010 and 22011, were delivered in July 2007 with corrosion damage received in transit from South Korea. IÉ did not accept delivery and stored the sets until October 2008 when they were returned to Rotem for repair, with a revised delivery date of early 2009. It was later determined that it was uneconomic to repair them, so Rotem added
