I am advised:

The Government has been playing catch-up after 16 years of underinvestment in public transport infrastructure under Labor. The government is investing more than $1.1 billion annually in rail maintenance and has delivered a range of infrastructure projects and operational initiatives to improve performance. These include:

The procurement of new intercity fleet, which will replace the current rolling stock carrying customers between Sydney and the Central Coast and Newcastle. The new fleet will offer improved reliability and performance, with the first trains anticipated to be delivered in 2019.

The 'Fast-track Platforms' program which addresses train dwell-time management at key CBD locations.

Track works and junction remodelling at Hornsby, which will provide greater flexibility and improved separation of service types in this area.

New track, such as the Epping to Thornleigh Third Track, which assists in the separation of different service types, including longer distance passenger and freight services.

The Gosford Passing Loops project which has improved reliability in that area by separating train services and providing opportunity for faster services to overtake slower services.

The opening of a purpose-built Newcastle Interchange, replacing the current temporary terminus at Hamilton, which will improve reliability through the availability of more platforms and specially designed signalling to maximise timetable flexibility.
