Armadale and Thornlie Line passengers are being urged to plan ahead, with a 17-day disruption on the Armadale and Thornlie lines just six weeks away.

The disruption, which will run from January 6 to 22, will allow important works on to be carried out on railway infrastructure for Perth Stadium Station.

Transperth spokesman David Hynes said trains would operate at significantly reduced frequency.

“The Armadale Line will run at a 30-minute frequency on weekdays with Thornlie Line services – and some weekend and all weeknight Armadale Line services – replaced with buses,” Mr Hynes said.

“We’ve planned this latest series of works on Perth Stadium Station to coincide with the quietest time on the Transperth network – the post-Christmas period, during school and university holidays, and outside AFL season.

“Works to complete Stadium Station and the Victoria Park stow roads, which will enable up to 28,000 passengers to leave the Perth Stadium within an hour of an event, cannot occur without the disruption.

“Due to the complexity of the track works, and the need for trains to switch to a different set of tracks, Armadale Line passengers will need to change trains when they pass through Carlisle Station, and the Mint Street level crossing will close for the duration.”

Passengers are being encouraged to plan ahead, consider alternate travel options, take a holiday or work from home and, if they must use public transport to leave extra time and prepare for delays, as trains will be limited and journey times longer.

Work on the station site is now 70 per cent complete. A time-lapse of the project can be viewed here.
