Nomenclature
Prior to 1996, the Inner West line was considered part of the Bankstown Line and was coloured brown on promotional material and directional signage. A timetable named Parramatta Line carried details of all services between Parramatta and the City, including Northern, Southern, Western and Bankstown line services. The section between Lidcombe and Cabramatta via Regents Park was considered part of the Macarthur Line (what is now the South Line), and was colour-coded green. From 1996, when the Merrylands to Harris Park Y- Link opened and the timetable was re-written, the Lidcombe to Cabramatta via Regents Park section was colour coded brown and a new timetable labelled Liverpool- City via Regents Park was published. The August 1999 timetable revision saw the term Inner West Line used for the first time, and the line was colour coded purple which it has maintained to the present day.
