IE management may not be aware of the PPT - but developers are aware of the value of Liffey Junction and Islandbridge (old keg loading area and carpark) landbanks and all the other smaller brownfield sites along its course. Now that the Interconnector funding is secured, CIE are no longer keeping the PPT secret anymore as the PPT can't be used as a political football. It's no longer a "works tunnel", and it no longer needs to be played down. Regular passenger services will be operating through the Phoenix Park tunnel within the timeframe of T21.
