Thousands of commuters in Sydney's southwest will soon have access to new rail stations, which will open a year ahead of schedule.
Two stations - at Leppington and Edmundson Park - will open on February 8 after more than three years of construction and months of testing.
Eight trains will run every 30 minutes from Liverpool to Leppington, stopping at Edmundson Park and Glenfield.
Commuters will be able to change trains to connect with services across Sydney, including the CBD and Parramatta.
NSW Premier Mike Baird says the South West Rail Link opens $300 million under budget.
"The good news is, we have found the money, done the construction and testing, now it's under way," he said on Thursday.
"It's what southwestern Sydney needs."
Parking spaces will open alongside the stations and new bus routes will include the stations as stops.
