A new text alert system for Dart passengers is getting more than 60 messages a month.
The system, which alerts security staff to anti-social behaviour, was set up after an increase in incidents on trains.
145 passengers used the new text alert system from when it was launched in mid August to October 18th according to figures released to the Irish Times.
That's an average of more than 60 messages a month, or more than twice a day.
54 were about teenagers involved in anti-social behaviour, 42 reported passengers taking drink and drugs while there were two complaints about sexual harrasment and one about racism.
Passengers also complained about fireworks being set off on-board, vandalism, smoking and begging.
A number of people who used the service said they got an automated response but were never updated on what action, if any, was taken.
Members of the public can text the word TRAIN followed by their location, carriage number, and details of the incident to 51444.
The service is expected to be rolled out to commuter services in the coming weeks.
