The National Bus and Rail Union is calling for a dedicated Garda Public Transport Division.
The union has renewed calls for the division on the back of increasing anti-social behaviour.
Figures obtained by RTÉ show there have been 573 reports of anti-social behaviour and 11 assaults on Irish Rail staff up to September 9th this year.
The news comes as a DART ticket checker was attacked with snooker balls in a sock.
Darren (whose surname was withheld), sustained concussion and was treated at Beaumont Hospital.
Meanwhile, Fianna Fáil Spokesperson on Transport Robert Troy has called on Trasport Minister Shane Ross to immediately address the anti-social behaviour on public transport.
"Both Irish Rail workers and passengers are regularly left distressed and inconvenienced by reckless behaviour. Arguments, brawls, people carrying weapons and general soiling of the carriages are all regular occurrences," said Mr Troy
"There are workers who are petrified as they begin their shifts each day and there are passengers who avoid public transport at all costs as a result.
"Minister Ross needs to take urgent action for the sake of Irish Rail staff and passengers. He needs to engage with Justice Minister Charlie Flanagan on this issue to discuss and coordinate a response to these attacks."
