Tech upgrades to bring more trains and services on T4 and T8 lines

Published: 12 Jun 2018

New state-of-the-art signalling and control systems will lead to more peak-hour train services on the T4 Illawarra Line and T8 Airport Line.

An $880 million technology investment from the NSW Budget 2018 will modernise the Sydney Trains network and allow eight more services an hour during peak periods on the T8 Airport Line at the International, Domestic, Mascot and Green Square stations. On average a train will arrive every four minutes instead of every six, along with extra services from Revesby.

Five more trains an hour will be added during peak periods on the T4 Illawarra Line from Cronulla, which is an increase of up to 30 per cent in capacity.

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

Premier Gladys Berejiklian said the current rail network is complex and relies on old technologies, which limits the number of services that can be provided.

“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,” Ms Berejiklian said.

“The T4 Illawarra Line and T8 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.”
