The Kildare Route Upgrade project provides for the replacement of the Cherry Orchard station by a new station at Parkwest to be constructed by developers at no cost to the taxpayer. This will be completed ahead of the main Kildare Route Project itself. The relocated station will be 900m west of the existing Cherry Orchard station.
I understand from Iarnród Éireann that the reasons for this relocation are that the timetable improvements that the project will deliver could not be achieved if the existing station locations in the area were used and that a number of technical difficulties would arise if the station is not relocated.
