According to a report in the Irish Independent, Franks said that 'one of the biggest contributions we can make to the economy is moving people over long distances and into city centres fast.'
Frank added that Irish Rail could run intercity services direct to the airport, or else link the airport and city by DART before switching to intercity trains.
Failte Ireland revealed recently that Dublin is targeting an 8% increase in meetings in 2015, which will create an estimated £43m in economic impact for the city.
