Sydney Trains will be undertaking maintenance work at Westmead from 7am Friday 20 April to 5pm Monday 23 April.
To improve service reliability and reduce the need for ongoing maintenance, NSW Transport is working on track reconditioning.
During this time, work vehicles will access the rail corridor via Hawkesbury Road overbridge and Railway Parade, Westmead.
A single lane on Hawkesbury Road will be closed.
Parking and a single lane of traffic will be impacted on Railway Parade.
Traffic controllers will be on duty to direct motorists throughout the duration of the works.
While NSW Transport parks their vehicles inside the rail corridor, please be aware that on-street parking may be limited near work sites.
These works may create additional noise at night and over the weekend.
To find out whether buses will replace trains during this work, please call 131500 or check Upcoming Trackwork on the transportnsw.info website.
