$72m train station opens in Perth

A $72 million train station has opened at Aubin Grove, in Perth's south, with the service expected to be used 3900 times a day.

The station, between the Cockburn Central and Kwinana stations on the Mandurah line, was opened on Sunday by Premier Mark McGowan, who acknowledged the former Barnett government's role in the project.

"This will help take cars off the road, it'll make the Kwinana Freeway less congested," Mr McGowan told reporters.

"Get on the train, enjoy the experience, save money, get to the heart of the city, get close to home, it's the right way to go."

The station features 2000 parking bays, bike facilities, six bus feeder services for locals and a kiosk.

Its opening has created 17 full-time equivalent jobs, while about 100 jobs were created during construction.

The combined cost of the Aubin Grove road and rail project is $125 million, including $20 million in federal funding.

Transport minister Rita Saffioti said the station was built while the Mandurah line was largely still operational.

"This project represents a feat of engineering, with the station largely constructed off-site and then sections craned into place over the last 18 months," she said.

"Several off-peak weeknight and night closures were required so that overhead power could be switched off to make it safe for workers in the rail zone."
