The Airport & South Line (numbered T8, coloured green) (commonly called the East Hills Line) is a suburban commuter rail line in Sydney, Australia. It connects the Sydney central business district with the southwestern suburbs via Sydney Airport. The line is part of the Sydney Trains network. The line began operating on 26 November 2017, when the T2 Airport, Inner West & South Line was split in two. Sydney Trains' predecessor CityRail operated the Airport & East Hills line over an identical route between 2000 and 2013.
