Major scope improvements made – since June 2011

Fully funded from State budget – $806m FY2013-14, $4 billion over next 4

Property acquisitions well advanced – >85% of transactions completed

EIS 1 approved September 2012 ; EIS 2 approved May 2013

Early construction works managing contractor appointed – August 2012

Tunnelling contract (TSC) awarded – June 2013

Surface viaduct and civils contract (SVC) tenders received – August 2013

Shortlist of two consortia for operations (OTS) PPP announced – May 2013

On program for the first of the TBMs in ground in 2014

State Plan

Budget Planning Transport Rail

State Infrastructure Strategy

Aligned with State strategies

The plan: Sydney’s Rail Future

The plan: delivered in five stages

Stage 1 Operational efficiencies

Stage 2 Network efficiencies

Stage 3 Rapid transit: North West Rail Link

Stage 4 Rapid transit: New harbour crossing

Stage 5 Rapid transit: Southern sector conversion

Artist’s impression: Castle Hill Station

The stations Bus interchanges, taxi ranks, bicycle storage

Easy access, kiss-and-ride

Safe, well-lit environments, constant CCTV monitoring

Passenger screen doors

No timetable – just turn up and go. “

Artist’s impression

The trains Single deck, no internal stairs, three doors per carriage

1,300 capacity

Automated, modern technology

“ Clear and constant communications with customers.

Artist’s impression

Automation Safety No. 1 priority

Platform screen doors: train operations faster and safer

Constant live monitoring by expert train controllers
