IE 22000 CLASS

(Redirected from 22000 Class)


The '22000 Class' are the latest Diesel multiple unit trains to be introduced by Iarnród Éireann in Ireland.
In a new departure for Iarnród Éireann they will be the first railcars to operate on express InterCity routes. Together with the recently introduced Mark 4 coaches they will give Iarnród Éireann one of the most modern express fleets in Europe.
Supplied by Mitsui of Japan in an order totalling approximately €400 million, the fleet is being 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.
The initial order for 120 vehicles was increased to 150 in 2005 for InterCity services. In March 2007, a €79 million order was placed for a further 33 vehicles to be used primarily on the outer Dublin commuter network. There are to be 46 sets in all: 31 3-car sets and 15 6-car sets of two different layouts
