Passengers are being urged to report antisocial behaviour on DARTS in Dublin through a new text alert service.
You text the word TRAIN followed by the location, carriage number, and details of the incident to 51444.
It'll be sent to a live, monitored security centre during operational hours which can then contact security teams.
Iarnrod Eireann spokesperson, Jane Cregan, says they want to help people experiencing the problems onboard or in stations.
The new service is being publicised on displays on Dart carriages and in stations and will be further extended to Dublin Commuter routes in the coming weeks.
Last year, more than 560 passengers made formal complaints about intimidation, vandalism, assault, begging and theft on Irish Rail services. Complaints about antisocial behaviour on the Dart almost doubled to 96 from 52 the previous year.
