[1] Navan Road Parkway (formerly Phoenix Park) opened nearby in 2008 but does not replace Ashtown.

A major grade-separated junction was built on the R147 to provide access to Navan Road Parkway.

The station was opened by the Midland Great Western Railway in 1847 for race specials at the now-demolished Phoenix Park Racecourse.

The line through the station was then nationalised, passing on to Córas Iompair Éireann as a result of the Transport Act 1944[2] which took effect from 1 January 1945.

Under this management, it reopened briefly in 1979 for the visit of Pope John Paul II to Ireland in order to facilitate the large numbers who attended the open-air mass in the Phoenix Park and reopened permanently on 11 January 1982.
