[citation needed] Erindale was most recently upgraded and is now fully wheel chair accessible.

A construction project underwent a new multi-level covered parking structure with 1700 new spaces, new bus loop, dedicated pedestrian pathways, and covered pedestrian bridge to the station tracks.

With the decline of passenger traffic on the line, the old Erindale station was demolished in the 1950s.
