150 of these three/six-car diesel railcars are currently being delivered and entering service on Irish Rail. They are the first intercity railcar fleet to be ordered since the AEC railcars of 1952. The 22000 Class have begun operating on Dublin-Sligo-Limerick services, and will shortly take over Galway, Rosslare ,Waterford and Westport line trains. A further 33 of these units will be delivered to operate mainly on Dublin suburban services. Some sets will also work on Cork-Tralee line trains.

The 22000 Class railcars are purpose built for intercity services unlike previous Irish railcar designs, and have a top speed of 100mph, carrying also the newer livery of Irish Rail of silver and green, complete with 'Intercity' logos.

Built: 2002 & 2005 by CAF*, Spain.

20 of these four-car diesel railcars were delivered to Irish Rail in 2002, with a further 9 arriving in 2005, becoming one of Ireland's most numerous class of railcar. Originally numbered as the 2900 Class, the later batch delivered resulted in them been reclassified as the 29000 Class, in order not conflict with NIR's 3000 Class units.

The railcars entered service branded in the new IE 'Commuter' livery from the offset, and began operating suburban services north to Drogheda and Dundalk, west to Maynooth, and south to Arklow and Gorey, displacing loco hauled services and earlier built railcars on these trains. Unlike previous two car designs, the four car 29000s have non-gang way ends resulting in a somewhat pleasing streamlined front. The class also briefly worked Intercity services between Dublin & Sligo, until displaced by 22000s.

20 of these two-car diesel railcar units were delivered in 2000 to Irish Rail. Bearing the similar features to the earlier 2600 and 2700 Classes these railcars were once again branded as 'Arrow' and carried briefly the original black & orange livery, before been re-branded as 'Commuter'.

Operating firstly on the main western suburban lines out of Dublin to Kildare and Longford, these units were also largely displaced by 29000 Class railcars. They were later used on Intercity services from Dublin to Rosslare, before been displaced by the newer purpose built 22000 Class railcars. They still however operate services to Mullingar and Longford.

27 of these one/two-car diesel railcar units were delivered in 1999. Following the success of the earlier 2600 units, the 2700s followed a similar pattern, built mainly for commuter services. Branded as 'Arrow' and carrying the same orange and black livery, superseded later by 'Commuter' livery, these units operated suburban services to Kildare and Drogheda, and even further a field to Longford.

Displaced by later 29000 Class railcars, the 2700s also now operate cross country services between Limerick-Rosslare and Cork-Mallow-Tralee, displacing loco hauled services in these areas.

40 of these two-car electric multiple units were delivered to CIE for use on the new electrified route of the DART system between Bray & Howth in Dublin City.

Delivered in 1984 in an attractive apple green livery, complete with CIE broken wheel logo, these units became an immediate success with Dublin commuters north and south of the Liffey. The 8100 Class units were initially formed of four/two-car trains, but with the ever increasing passenger numbers using the DART service, the class can now be normally seen in 4/6-car trains. Originally fitted with 72 seats, complete with side 'tip up' seats, these were removed in the late 1980s to increase standing space and resulted in an extra removal of 16 seating areas.

The DART logo was applied just prior to official launch in 1984. It wasn't until 2000 that the original green livery on the 8100 Classes was changed, with yellow warning panel and two tone green side stripes been applied. The 8100s can now also work in multiple with the Japanese 8500 Class built units.

Refurbished 8100 Class DART units.

By 2004, the 8100 Class units had become 20 years old and have suffered 'wear & tear' over the number years in service. Several units of the class have, and are still currently being overhauled by Siemens, Germany.

The refurbishment involves the installation of modified marker lights utilising a 'cluster' design, removal of some seats to add even more standing space, installation of an electronic passenger information system and door closing warning beeper. Only a few original LHB DART units remain, out of service and awaiting overhaul.

With ever increasing passenger numbers using the DART service, and with the extension of electrified services to Greystones & Malahide, Irish Rail ordered 10 two-car electric multiple units from CAF Spain. These units carried the present day DART livery on entering service on Irish Rail.

Not the most popular DART trains, due to lack of space and frequent maintenance, most of the 8200 Class units were out of service by 2007, pending overhaul at Irish Rail's Inchicore Works, Dublin. The 8200 Class sets however have since begun to re-enter service on DART services.

Built: 2000-2005 by Tokyu Car Corporation, Yokohama, Japan.

To expand the electrified DART fleet even further, Irish Rail ordered 60 8500 Class units between 2001 & 2005. These DART units are by far the most numerous class, and have a built up a good reliability record.

These units were also delivered in the new DART livery of two tone green with yellow warning panels, complete with a revised DART logo. There are some slight differences between some units in the 8500 fleet, mainly the curvature of the roof profile. Popular due to space and comfort, the 8500s can also work in multiple with the earlier 8100, and 8200 Class DART units. The 8500s also work services to both to Malahide and Greystones.
