Artist’s impression: Kellyville Station street view
Bigger than the Harbour Bridge
Eight new railway stations
4,000 car parking spaces
A train at least every five minutes in the peak
15km twin tunnels
4km skytrain viaduct
20,000 more tonnes of steel than the Sydney Harbour Bridge.
The longest rail tunnels built in Australia. “
Artist’s impression: an underground station
More trains, more choice
Australia’s first fully-automated rapid transit rail system
Fast, safe and reliable single deck trains
Conversion and upgrade of Epping to Chatswood line
Bringing the project to life Widespread community engagement – since June 2011
Project aligned with key Government plans, Transport Master Plan
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: 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
Heating and cooling in underground stations. “
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

Artist’s impression: Cherrybrook station aerial view
Automation Clear communications
Multiple cameras and help points, inside trains and out
Staff moving through the system during the day
Australia’s first fully-automated rapid transit system.
Automation
30 years of operations
588km, 41 lines, 25 cities, 585 stations, 4 continents
Impressive safety record
