NSW Premier Gladys Berejiklian has promised to begin constructions on the proposed Metro West rail line next year, ahead of the state election late this month.

Ms Berejiklian said, if re-elected, the coalition government will commit $6.4 billion to the transport infrastructure project, which is expected to decrease travel times between Parramatta and the Sydney CBD to 20 minutes, with trains running every two minutes.  

“We always said we would build Metro West as fast as possible and today’s announcement shows we mean business,” Ms Berejiklian said on Sunday. 

“Metro West will more than double the existing rail capacity between Parramatta and the Sydney CBD,” she added.  

As part of the project, new railway stations will be built in Five Dock, Burwood North and the Bays Precinct as well as in suburbs that already have stations, including Parramatta, North Strathfield, Westmead, Sydney Olympic Park and the City. 

The government is also looking into possible stations between Olympic Park and Parramatta such as Rydalmere as well as at Pyrmont. 

Metro West is expected to take about eight years to finish from the start of construction, although the project schedule will only be confirmed after the final business case has been completed.
