Iarnród Éireann (Irish Rail, the state railways of Republic of Ireland) class 29000 commuter DMU train at Docklands station in Dublin. It's a four coaches long fixed DMU. They were built by CAF in Spain in two series, 2002 and 2005. Irish Rail got 29 trainsets of this type.

On the left another class 29000 DMU train and on the right one of the new class 22000 Intercity trains. The class 22000 trains were built by Hyundai Rotem (trainsets) and Tokyu Car Corporation (bogies). They operate now on the majority of long distance Intercity services in Ireland.

A better picture of one of the class 2200 Intercity trains. Irish Rail ordered 63 of these trains and they are formed in 3, 4, 5 and 6 coaches long trainsets, built from 2007 onwards. The last train was delivered in 2012. These trains have a top speed of 161 km/h (100 miles/h) and they are powered by MTU 6H 1800 R83 diesel engines, which are powerful but quite noisy.

Irish Rail class 2800 trains looked like a train moving without a locomotive when they were new. These trains have been used mainly in the service branded "Commuter". They were built from 2000 onwards in Japan by the Tokyu Car Corporation. Two coaches form one trainset. It's a diesel multiple unit and each trainset has 85 seats. 10 trainsets were built.

Class 2800 trains were modernised and during the modernisation the possibility for passengers to move from one unit to the next one in a moving train was removed and the front parts were redesigned. All these trains were transferred to the region around Limerick where they operate on short Intercity routes as well as Commuter routes.

This is a Córas Iompair Éireann 8100 Class train. This was the first train type that entered the DART services around Dublin. Here we see this individual already after it was thoroughly modernised. They were built by General Electric and Linke-Hofmann-Busch in 1983 and they were the only trains on the DART services before the class 8200 was delivered. There were 40 two-car sets with 176 seats per trainset. All the units were heavily modernised and rebuilt by Siemens in 2007. In 2022 Irish Rail started a public tendering in order to replace these trains with bimodal (diesel + 1500V DC) trains to be called class 9000.

The class 8200 trains were two coaches long units with one motorised and one unmotorised coach running with 1500V DC overhead intended for the DART service (Dublin area rapid transit service).
There were only five sets ever built and the builder was Alstom. They entered service in year 2000 and were long periods out of service due to numerous technical failures. They were offered for sale in 2012 but nobody wanted to buy them. 2023-24 they were scrapped.

Two more of the same class 8200 trains. The following year they were offered for sale. But when a train is known to be problematic, is running on a rare 1600 mm gauge and with a rare 1500 V DC, there are not many places in the world where someone would want them.

These DART trains were built by Tokyu Car Corporation in Japan in three series, 8500 class in year 2000, 8510 class in 2001 and 8520 class 2003-2004. These classes have only minor differences. This individual coach number 8635 is an unmotorised driving trailer coach of the newest series. There are always four coaches in a trainset, two of which are motorised. Altogether there are 17 trainsets in use on the DART services around Dublin. They operate on 1500 V DC overhead and have a top speed of 110 km/h.

This shows how the four coaches long class 8520 trainsets are being used in DART traffic to form really long trains.

Iarnród Éireann old orange express train coaches. These are normally not used anymore. These are the so called Cravens coaches built in 1963 and used until 2006.

Ireland has very few locomotives left. This number 209 lurking from the depot door is one of the class 201 locomotives which used to pull for example the trains between Dublin and Belfast in Northern Ireland, but now also that service has been switched over to diesel multiple units. Locomotives are mostly needed only for track reparation works anymore. These class 201 machines were built in Canada by GM-EMD 1994-95 and there were 34 of them, 32 for Irish Rail and two for the railroads of Northern Ireland. It is a six axle machine with an EMD 12-710G3B turbocharged 12 cylinder engine giving it a theoretical 3,200 hp (2,400 kW) power rating and a top speed of 164 km/h.

Dublin has a tram system called LUAS. Luas is Irish and means speed. There are two main lines, green and red with some branches. The system operates on normal gauge (1435 mm) tracks with 750 V DC using Alstom's Citadis trams. This one is a class 4000 tram, which is one of the original class 3000 trams lengthened by adding two more sections. These are Alstom Citadis type 402 trams. The newest ones which are called in Dublin class 5000 are trams lengthened twice to be similar with Alstom's type Citadis 502 and they are now 55 metres long. The Citadis 402 version that we see in this picture is 43 metres long.

Dublin's Citadis trams are bidirectional and have doors on both sides.

Dublin's Citadis trams were originally all like this, 30 metres long and called class 3000. After one lengthening they became 43 metres long class 4000 trams and now after yet another lengthening they are called class 5000 being 55 metres long. But they are otherwise still similar.

Tickets for the trams can be bought from this kind of vending machines outside on the streets.
