Once complete, the city-shaping Metro West will link Westmead to the Sydney CBD through Parramatta, Olympic Park and Five Dock in a 22-minute trip. Commuters will be able to move from Westmead to Parramatta in two minutes, reach Pyrmont in 20 minutes and arrive at Hunter St in 22 minutes.
Premier Chris Minns said, "this is an exciting milestone in the delivery of the Sydney Metro West project. With this breakthrough at what will become Westmead station, we are well on the way with this city shaping piece of transport infrastructure."
TBM Betty worked around the clock for 2 years at a progress rate of about 200 metres a week to build the nine-kilometre tunnel from Sydney Olympic Park. During that time, it chewed through 790,000 tonnes of earth and lined the tunnel walls with 30,000 concrete segments along the way.
A crew of up to 150 workers at a time have spent three years building the 500-metre underground cavern at Westmead. It is the deepest station on the Metro West line, at up to 39 metres below ground.
The remaining sections of tunnel are being worked on by three TBMs: TBM Dorothy is 1,059 metres from its final breakthrough at Westmead, where it is due to arrive in the coming weeks. At the opposite end of the alignment, TBMs Ruby and Jessie are making their way under Sydney Harbour to reach the Hunter Street terminus in the Sydney CBD by the end of the year.  
“Seeing the first tunnel reach the end of the line, and the project’s furthest point west, is a moment to celebrate as the community here in the heart of western Sydney looks forward to its own Metro line," stated Minister for Transport John Graham.
The line is on track to open in 2032, Premier Minns confirmed, with new stations at Westmead, Parramatta, Sydney Olympic Park, North Strathfield, Burwood North, Five Dock, The Bays, Pyrmont and Hunter St.
WESTMEAD STATION
New metro platforms will be located next to the existing Westmead Station providing an easy above-ground interchange with the T1 Western Line and T5 Cumberland Line. The new station will also provide customers with easy access to Parramatta Light Rail, T-way buses and other bus services. As well as connecting customers to the Westmead health, education and employment hub, the new metro station will service residential areas experiencing growth and renewal in north and south Westmead.
PARRAMATTA STATION
Strategically located to the north of the existing Parramatta Station, the new metro station will be within the commercial core of the Parramatta CBD, taking pressure off the existing station and giving customers a second rail option. The new metro station will integrate with the proposed Civic Link, a green, pedestrianised public space from Parramatta Square in the south to Parramatta River in the north.
SYDNEY OLYMPIC PARK STATION
A metro station at Sydney Olympic Park will reinforce its status as Australia’s premier events, sporting and entertainment precinct, supporting the transit of more than 10 million people who visit or stay each year. The metro station will be located to the south of the existing Olympic Park Station, providing easy interchange with the planned Parramatta Light Rail, the T7 Olympic Park Line and buses.
NORTH STRATHFIELD STATION
The station will improve connections to key employment and education precincts and take the pressure off Strathfield Station. It will provide an easy interchange with the T9 Northern Line, opening up access to key centres in the north west like Norwest and Castle Hill via Epping.
BURWOOD NORTH STATION
Burwood North Station will strengthen the thriving business and retail centre to the south of Parramatta Road, and provide a new fast, frequent and reliable transport link for the community north of Parramatta Road.
FIVE DOCK STATION
The project will deliver rail to this area for the first time, providing for a fast and direct trip to Sydney CBD. The new metro station will provide for an easy interchange with the local bus network along Great North Road. The metro station will be integrated into the area and will align with recommendations of the local council’s Five Dock Town Centre Urban Design Study, building on Five Dock as a vibrant and friendly village to live in, work and visit.
THE BAYS STATION
The Bays Station will deliver rail to the area for the first time, providing critical connections to the Sydney CBD and the western suburbs. The Bays Station will act as a catalyst for the long awaited renewal of the area.
PYRMONT STATION
The new Pyrmont Station will be on the doorstep of Darling Harbour, Blackwattle Bay, the new Sydney Fish Market and the Sydney CBD. Pyrmont Station will greatly enhance plans to revitalise this inner-city precinct by encouraging jobs, investment and economic growth. The station will enable a new level of connectivity to the Pyrmont Peninsula and prioritise pedestrian movement through vibrant street frontages and open public spaces.
HUNTER STREET STATION
In the commercial heart of the Sydney CBD, Hunter Street Station will become a new hub with easy connections to George Street, Light Rail, Sydney Trains services at Wynyard and Martin Place and the new Sydney Metro City & Southwest station at Martin Place. A large vibrant precinct between George, Hunter, O’Connell and Bligh streets will prioritise pedestrians and support a vibrant public domain in the heart of the Sydney CBD.
