The East Hills railway line serves the southern and south-western suburbs of Sydney, Australia.

From Wolli Creek, the line heads west towards East Hills, where the alignment is within 2 km of the since-constructed M5 South Western Motorway.

It then turns south-west through the new suburbs of Voyager Point and Wattle Grove to meet the Main South line at Glenfield Junction.

The bridge over the Georges River at East Hills, opened in 1987, is the only significant engineering structure on the line.

Residents west of Salt Pan Creek petitioned the government to extend the line to East Hills.

[1] A ceremony at Padstow Park commemorating the turning of the first sod by the then-Premier of New South Wales Jack Lang was held in September 1927.

[11] The line was duplicated between Kingsgrove and Riverwood in 1948, with points for terminating trains provided at both stations, and a passing loop at Revesby was opened in 1956.

Services generally ran all stations from East Hills via Tempe and Sydenham, to the City Circle.

Local (all stations) trains generally were timetabled to run from East Hills via the airport, peak hour express trains from Campbelltown run along the original route via Sydenham, taking the express tracks between Kingsgrove and Wolli Creek Junction.

From October 2009 it replaced East Hills as the primary turn-back point for local all-stations services on the line.
