More than 60 incidents of train or tram surfing have been reported by Irish Rail and the operators of the Luas light rail system over the past three years.
The dangerous practice, also known as "scutting", involves a person holding on to the outside of a carriage as it moves away from a station.
The problem is far more prevalent on Dart services than anywhere else, according to a database of incidents released by Irish Rail.
A single incident of train surfing was reported on the Northern Commuter line, the records show.
However, 55 separate incidents were recorded on Dart services on both sides of the River Liffey.
According to a log released under Freedom of Information, there were 20 reports of tram surfing in 2018, 32 incidents last year and three so far this year.
For the 19 incidents where an exact location was provided, the highest numbers were at Salthill and Glenageary (three each), both in South Dublin.
A spokeswoman for Irish Rail said it had put in place a number of mitigation measures to try and deter people from train surfing.
"We include a requirement in new vehicle specifications for manufacturers to consider this in the design to seek to prevent or minimise the risk," she said.
Irish Rail said when trains from the fleet are refurbished, steps are taken to "remove the surfing area".
The number of instances of "scutting" on Luas trams has dropped dramatically in recent years. In 2018 there were six reports of the practice and last year that had fallen to a single incident on the Green Line.
A spokeswoman for Transdev, which operates Luas services in Dublin, said incidents had been low in recent years.
"While the number of incidents associated with tram surfing are very low, our message is still the same - if you witness a person surfing, call the gardai immediately," she said.
One of the most notorious instances of "scutting" took place on a Luas service where a young girl suffered life-changing injuries after falling from a moving tram.
Rebecca Kelly, who was 13 at the time of the incident in 2010, settled her case for €550,000 while accepting what she did was a "silly thing".
