Problem to be addressed
Strong economic and population growth in the Greater Sydney Region has significantly increased demand for rail services. In 2018, the T4 Illawarra, T8 Airport and South Coast lines catered for 410,000 round trips per day, or one third of Sydney Trains customers.
In 2018, 75% of T4 AM peak services and 54% of T8 AM peak services operated above target operating capacity. This made these services the most and fourth-most crowded lines on the Sydney network respectively.
Strong population growth is expected over the next 40 years. Without intervention, this will continue to increase demand for rail services and expose the key capacity constraints of Sydney’s transport network.
This project is Stage 2 of the multi-stage More Trains More Services (MTMS) Program to increase rail capacity across the Sydney network. MTMS Stage 2 will include enabling works on the T4 line, including:
- additional turnback capacity at Sydney’s Central Station
- new crossovers at Erskineville and Hurstville
- station capacity upgrades and platform lengthening.
On the T8 Airport Line, the project will upgrade signalling, increase train maintenance storage capacity, and provide station upgrades and traction power upgrades.
In addition to the track and rail improvements, 17 eight-car double-deck suburban trains and 30 New Intercity Fleet cars will be procured.
It is expected that the project will result in more services to provide more regular and reliable services on the T4 and T8 suburban lines.
