Irish Rail is warning passengers that fraudsters are masquerading as ticket inspectors and collecting on-board fines on the DART.

The rail company is urging people to demand ID when approached for tickets or issued with fine on the Northern Commuter and DART services.

It said the fraudsters are wearing non-Irish Rail Hi-Viz vests.

In a post online, Iarnród Éireann said: “Passengers are advised that there are members of the public wearing non-Irish Rail hi-vis vests and masquerading as members of the RPU (Revenue Protection Unit) onboard the Northern Commuter/DART line.”

“Passengers are advised to confirm ID when approached for tickets/being issued with onboard fines.”
