The NSW Government will not proceed with proposed timetable changes for the T4 Eastern Suburbs & Illawarra, T8 Airport & South and South Coast lines following feedback from passengers, local communities and MPs.
The changes had been scheduled to take effect on 15 November 2026 and were intended to increase service frequency, capacity and reliability across southern Sydney and the Illawarra.
Under the now-cancelled plan, the T4 and South Coast lines would have used separate express tracks between Arncliffe and Central, while some stopping patterns and journey times would also have changed.
The NSW Government said concerns raised by commuters and affected communities had prompted the decision not to proceed with the November timetable.
Existing Timetable to Remain
Passengers on the T4, T8 and South Coast lines will continue travelling under the existing timetable while Transport for NSW considers future service changes.
The government said further timetable improvements would be developed with greater consideration of passenger feedback and the performance of the existing rail network.
No new implementation date has been announced for revised changes.
Focus Shifts to Rail Reliability
The decision comes as Transport for NSW continues work to improve reliability across the heavy rail network.
The 2026–27 NSW Budget includes $2.1 billion for rail maintenance, signalling, systems and station upgrades, alongside additional investment in incident response and service recovery.
The funding includes track, power and signalling improvements, upgrades to the Rail Operations Centre and additional incident-response capability.
These measures follow an independent review into major Sydney Trains disruptions in 2025, which recommended more targeted maintenance in high-risk sections of the network.
While Sydney’s Metro network continues to expand, the existing heavy rail system remains a major part of the city’s public transport network, carrying more than one million passengers on a typical weekday.
Transport for NSW will continue reviewing future timetable changes for the affected lines, with the existing services remaining in place in the meantime.
