Built by Alstom in Poland, they are due to undergo testing in depots and on the rails before introduction.
The trains were purchased in two orders as part of a framework agreement which provides for up to 750 electric/battery electric carriages over a ten-year period
The sets have battery packs, so they can travel on track that hasn’t been electrified yet.
The fleet orders, funded by the National Transport Authority (NTA) under Project Ireland 2040, are part of the wider DART+ Programme.
DART+ is a series of infrastructure projects which, together with train orders, will double the capacity and treble the electrification of the Greater Dublin Area’s rail network.
The National Transport Authority are working on proposals to install a terminal charging point at Wicklow Town.
Irish Rail CEO Jim Meade says the line from Dublin Connolly towards towns in Louth will be utilised in the meantime.
