Number of trains which can run during the morning and afternoon peaks on the Illawarra Line and Airport Line will be increased, following an $880 Million investment in technology improvements to modernise the Sydney Trains network.

Premier Gladys Berejiklian said funding in New South Wales Budget 2018 will allow for 5 more trains an hour during the peak on the Cronulla Line, which is an increase of up to 30 % in capacity.


Technology improvements will also allow for 8 more services an hour on the Airport Line at the International, Domestic, Mascot and Green Square stations, meaning trains at least on average every 4 minutes instead every 6, along with extra services from Revesby.

These upgrades will be delivered in stages with services coming online progressively from the early 2020’s.

“At the moment our rail network is complex and reliant on old technologies which limits the number of services we can provide.” Premier Berejiklian said.

“That is why we are making significant investments to improve rail infrastructure and ensure we can continue to meet the growing demand for rail services.”

“Illawarra Line and Airport Line are the first beneficiaries of these signalling upgrades, which will be rolled out across the network significantly boosting capacity and reliability for all train customers.” Premier Berejiklian said.

Treasurer Dominic Perrottet said the investment in this technology was an important step in boosting capacity of existing Transport assets.

“We have all had the experience of waiting on an overcrowded platform, so this technology investment will contribute to increasing services and making journeys more comfortable.” Treasurer Perrottet said.

Minister for Transport and Infrastructure Andrew Constance said the program will start to upgrade parts of the network with state-of-the-art digitalised signalling and control systems used by some of the best railways around the world.

“We are investing in this signalling technology to get more trains on the tracks. Turning old rail into new rail.” Minister Constance said.

In response to recent growth in demand on the Illawarra and Airport lines the program will initially prioritise work to prepare the network to deliver:

  • Up to 30 % increase in peak suburban services on the Illawarra Line, as well as more services for South Coast customers.
  • More services for the Airport Line, including a potential 80 % increase at the International, Domestic, Mascot and Green Square stations during the morning peak, as well as extra services from Revesby and Campbelltown in south west Sydney.

“For future stages of More Trains, More Services, we’re also investigating how we can add extra services on other lines that we know continue to have high demand, like the Western and Northern Line.” Minister Constance said.

Initial investment of $880 Million goes towards developing and starting deployment of digital systems to replace legacy signalling and train control with modern, internationally proven, intelligent systems.

It will also be used for planning the initial stages of the Illawarra Line and Airport Line program, which over the next 10 years will deliver:

  • More services that will reduce wait times, meet demand and provide more seats for long distance customers.
  • Faster travel times for customers through digital train control technology and upgraded rail infrastructure, creating more opportunities for express trains.
  • Improved reliability and reduce customer impacts from incidents.

First phase of the More Trains, More Services’ program saw a capital investment of over $1.5 Billion by the New South Wales Government to provide a significant uplift in customer services on Sydney’s rail network.

Since coming to Government the New South Wales Liberals & Nationals have added an additional 30,000 public transport services.
