A number of Irish Rail services are experiencing delays on Friday morning due to an earlier “major” signal fault.

Services were suspended for a short time but are now operating again, though passengers have been warned of “significant delays” and alterations to routes.

Irish Rail says the services currently experiencing delays are: DART +50 minutes on some services; Northern commuter +15 minutes; Maynooth commuter +30 minutes; Phoenix Park Tunnel +10 minutes; Sligo +30 minutes and Belfast/Enterprise +35 minutes.

Irish Rail says the major signal fault across the Suburban Network which caused the suspension has been rectified.

There are also 25-minute delays expected on services between Kildare and Heuston. Earlier, an empty train broke down, blocking the line near Newbridge
