Irish Rail has urged passengers to be on the lookout for fake ticket inspectors as a warning has been issued following reports of false inspectors issuing on-board fines to people.
According to Iarnród Éireann, members of the public who have no affiliation with the rail service have been donning non-Irish Rail high visibility vests and pretending to be members of the Roads Policing Unit along the Northern commuter/DART line.
The rail service added that when it comes to anyone requesting tickets or issuing an onboard fine, it is advised you confirm the ID of the person requesting the ticket or fine money.

A spokesperson for the national rail service posted this update on their Twitter: "Passengers are advised that there are members of the public wearing non-Irishrail hi-vis vests and masquerading as members of the RPU onboard the Northern commuter/DART line.
"Passengers are advised to confirm ID when approached for tickets/being issued with onboard fines."
An Garda Síochána has been contacted for comment regarding fake inspectors and "are making enquiries into this".
People not purchasing tickets is a considerable issue for Irish Rail, and can cost the semi-state body thousands of euros every year.
If a legitimate ticket inspector asks you to produce a ticket and you cannot do so, then you can be legally issued with a Fixed Payment Notice, which means if you wish to avoid a court appearance and the possibility of receiving a criminal conviction, you may pay a fine of €100 plus your unpaid fare.
