Over 150,000 passengers look likely to be hit by an Irish Rail strike tomorrow.
Staff are walking off the job in a row over pay, as they seek a 3.75% rise to match Luas and Dublin Bus drivers.
However, management were only willing to offer a 1.75% increase during talks at the Workplace Relations Commission.
The stoppages will affect a number of services, including the DART and Commuter services.
It's the first of five days of stoppages and customers are being warned their train tickets will not be accepted on Dublin Bus or Bus Eireann.
Some of the other days strikes are planned for include November 14th when Ireland play Denmark in the World Cup Qualifier Playoffs at the Aviva.
They'll also down tools on December 8th, which is traditionally one of the busiest shopping days in the capital.
