The T8 Airport & South Line is a suburban rail service operated by Sydney Trains, connecting the Sydney central business district with the southwestern suburbs via Sydney Airport.
Since 2017, the line has been numbered T8 and is coloured green on maps and wayfinding information.
In March 2025, the federal minister for infrastructure, transport, regional development and local government Catherine King announced that a business case would be developed exploring a potential upgrade of the T8 Airport & South line.
History

The beginnings of the T8 service trace back to the opening of the East Hills railway from Tempe where it branched off the Illawarra railway to Kingsgrove on 21 September 1931. Electric trains ran from Kingsgrove via both lines to Central or St James, at a frequency of every 30 minutes during peak hours and hourly offpeak. The line was soon extended west to East Hills, with the official opening on 19 December 1931. This section was only single track and unelectrified, unlike the first section, so services were operated by CPH railmotor, supplemented by through steam trains from Central in peak hours.
The Kingsgrove to East Hills section was electrified on 17 December 1939, meaning the railmotor was no longer required and electric services could run direct from East Hills to the City.
With the extension of the East Hills Line to meet the Main South at Glenfield on 21 December 1987, only a small number of express services from Campbelltown to the City via East Hills were provided during peak hours. However by 1988, this had become a regular hour-hourly service.
On 21 May 2000, with the opening of the new Airport Link providing an alternative route between Turrella and the City, the East Hills Line received a timetable change, with most services diverted to run via the Airport Link instead of the Illawarra Line. Selected peak hour services continued on the old route via Sydenham. In 2002, the East Hills Line quadruplication from Turrella to Kingsgrove opened, allowing express trains to overtake local trains in this area.
With the formation of Sydney Trains in 2013, the service was rebranded and combined with other lines to become the T2 Airport, Inner West & South Line. At the same time, the extended quadruplication between Kingsgrove and Revesby was brought into use, further speeding up express services.
In 2017, with a new timetable, East Hills services were separated back out from the T2 into a new line, numbered T8. However, instead of returning to its original name, it was named the Airport and South Line. The former South Line became the T2 Leppington Line.
In September 2024, following the closure of the T3 Bankstown line for conversion into the Southwest Metro, a new T8 shuttle service between Sydenham and the City was added to serve St Peters and Erskineville which are not part of the metro conversion. This is temporary until these stations are moved to the T4 line as part of the Rail Service Improvement Program.
Operations
Stopping Patterns
Under the current (2024) timetable, there are generally three stopping patterns on the Airport & South Line:
- Express service: from Macarthur, stopping all stations to Revesby, then express to Wolli Creek, then all stations to the City via the Airport.
- Local service: starting at Revesby and running all stops to the City via the Airport. Some services start at East Hills.
- Sydenham service: from Sydenham, stopping at St Peters, Erskineville and Redfern
During peak hours, there are additional express services, which skip East Hills and Panania. Some also make additional stops at Padstow and Riverwood. Many express services also operate via Sydenham instead of the Airport.
- New South Wales A and B sets 8-car EMUs
- New South Wales T set 8-car EMUs – Weekends only

Patronage
Apart from the Airport Line's troubles, the line as a whole also suffered a substantial loss in patronage when the M5 East Tunnel opened in 2001. The tunnel joined the Eastern Distributor and M5 South Western Motorway, shortening road travel times between the city and the south-west. The line was estimated to have lost 384,450 commuters over 12 months after the tunnel opened. Since that time, however, the line appears to have gained commuters again, with a reported 3.5% increase in patronage up to early 2006.
The following table shows the patronage of Sydney Trains network for the year ending 30 June 2024.
