Harris Park station opened in the late 1800s.[3] Originally built as two side platforms, both were rebuilt as island platforms during the quadruplication of the Granville to Westmead line in the mid-1980s.[4] On 2 November 1996, the Harris Park to MerrylandsY-Link opened allowing direct train operation between these two stations by what is now known as the Cumberland Line.[5]
On 30 June 2013, a landslide occurred and a retaining wall collapsed in heavy rain, burying one track and partially covering platform 4.[6][7]
An accessibility upgrade, including lift access to the station, was announced in 2015.[8]
