Over 200 DART carriages have been vandalised since the start of the year costing over 500-thousand euro, according to a Fine Gael TD.
Data from Irish Rail shows 211 carriages have been damaged, with cleaning and repair costs amounting to 516-thousand euro.
Also in this time, 22 passengers reported youths causing disturbances. While there were 27 reports related to drink, drugs and smoking on trains.
Alan Farrell, TD for Dublin Fingal, says an increased Garda presence is desperately needed:
"It's not unique to Dublin. In order to tackle that and to make sure people safe on trains, and buses, I am calling for an increased Garda presence and a dedicated unit to be provided - to support the work of our transport providers and to ensure people feel safe on board."
