Dart commuters are being urged to stagger their journeys during the morning rush hour.
Irish Rail hopes a new initiative will reduce overcrowding on trains when people usually make their way to work.
Peaktime.ie will provide Dart customers with flexibility in their daily commute to find quieter trains in the morning peak.
A company spokesperson said. “Peaktime.ie will show commuters who are in a position to alter commuting times how a change of even ten minutes in some instances will find quieter trains.”
The information on the website will be expanded over the next few months to include all commuter trains in the greater Dublin area.
The spokesman said the initiative was being kick-started to coincide with the busiest commuting time of the year. That’s as third level students were going back to college.
