I had a look at kildarestreet.com and found the following;
Minister Varadkar is the 5th Minister for Transport since the Integrated Ticketing Project was started (not including Pat Carey's short reign).
Mary O'Rourke launched the Integrated Ticketing project for Dublin in May 1999.
Railway Procurement Agency (RPA) took over the project in 2002.
Seamus Brennan, in April 2004, stated that the Integrated Ticketing System (ITS) would be fully operational by 2005.
Martin Cullen said in March 2005 that ITS would be rolled out at the beginning of 2006.
Noel Dempsey, in June 2008, said that ITS would be launched in September 2009 and fully operational one year after that.
We are now well into 2011 and Minister Varadkar has stated that the system will be operational within a year. (last line here;

Perhaps the Minister should ask why previous attempts at estimate a finish date for ITS were so totally wide of the mark.
He risks making a fool of himself as the previous Ministers have.
