More Trains More Services is a program to modernise the rail network. 

Stage Two involves improving the T4 Illawarra, T8 Airport and South Coast lines by investing in infrastructure asset upgrades that remove key interdependencies constraining the network’s capacity. This includes the Digital Systems Program, which is intended to run across various stages, with the Stage 2 part of the Program encapsultating the T4 line.

Stage Two also involves enabling works for Stage Three and future stages, such as upgrades to the Sydney Central Terminal and trials of digital signalling systems required to deploy future timetable upgrades across the rest of the network.

More Trains, More Services Stage Two is designed to deliver a range of benefits for rail customers through digital systems, infrastructure upgrades and more new trains.

Key priorities of the MTMS Stage Two include:

• implementing digitalised train control and management systems
• enabling frequent, ‘turn-up-and-go’ services on the T4 Illawarra Line and T8 Airport & South Line, as well as improved services on the South Coast Line
• upgrading capacity at Central Sydney to support increased services
• infrastructure upgrades on the T1 Western and Northern Line to support increased services, and
• improved capacity on the South Coast Line to cater for future freight demands.

The NSW Government has invested an additional $1 billion in extra rail services as part of the integration of heavy rail with Sydney Metro City & Southwest in 2024. The extra rail services form part of the NSW Government’s $5.3 billion More Trains, More Services program that will deliver further improvements progressively from 2022
