from Clearway 3 to again run via Sydenham. The Airport Line would be served by all-stops East Hills Line trains from Clearway 4. St. Peters and Erskineville railway stations were expected to continue to be served by the Bankstown Line. This would have required platforms—partially completed in the 1970s from the Eastern Suburbs Line construction—to have been activated at these two stations. The works were cancelled in November 2008, and the plan for frequent operation of express East Hills Line services via Sydenham was abandoned. A second Bankstown Line project involved the construction of a new turn-back platform at Lidcombe, separating the Bankstown Line's operations from the former Inner West Line (later part of the Airport, Inner West & South Line). This works in concert with the Homebush turn-back project, which provides a terminating point for all stations trains on the Airport, Inner West & South Line. This separation was enacted in the October 2013 timetable. The turn-back platform at Lidcombe was also marked in 2012 as a terminal for Sydney Metro Southwest, with original plans to convert the Bankstown Line through to Lidcombe and Cabramatta into rapid transit. This plan has since been altered to have Bankstown as the terminus of the Metro line. Clearway 3: Campbelltown Express and Clearway 4: Airport & South The Campbelltown Express Clearway would have separated the section of the East Hills Line west of Revesby by quadruplicating between Kingsgrove and Revesby and sending express trains to the City Circle via Sydenham. This was to allow more frequent express services to the city, relieve pressure on other parts of the network and improve the distribution of passengers. On the Airport & South Clearway, express services would have begun at Glenfield and made their way through Liverpool, Cabramatta, Granville, Lidcombe and Strathfield stations to the City Circle, while all-stations services to the City started at Homebush. After passing through the City Circle, trains would have headed south-west via the Airport Line to Revesby (running parallel with the Campbelltown Express line from Wolli Creek to Revesby). In the October 2013 timetable, these two clearways were merged to create the Airport, Inner West & South Line. Differences from the original plan include via-Revesby and via-Granville trains sharing tracks between Glenfield and Macarthur, and all-stations and express trains via-Revesby sharing tracks between Revesby and Central. Most trains from Macarthur via Revesby use the local (pre-existing) tracks between Revesby
