Tens of thousands of Dubliners will have to find a different way to get around on Wednesday. No DART, Commuter or Intercity trains will run as Irish Rail workers strike over pay.
Workers want a 3.75% hike to match the Luas and Dublin Bus drivers. However, management are only willing to offer a 1.75% increase.
Wednesday is 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 services.
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, and December 8th, traditionally one of the biggest Christmas shopping days.
The Transport Minister has renewed his call to both Irish Rail and the trade unions to engage in constructive and realistic negotiations.
Shane Ross says it's important that public transport continues and the dispute is resolved in a fair and sustainable manner.
The Minister's urging the parties involved in the pay dispute to continue to use the services of the Labour Court and the WRC.
