Transperth services on the Mandurah train line will be cancelled at night between Perth and Cockburn Central stations next week to allow for maintenance works on the line.
The night closures will start on Monday October 30 and will last until Thursday November 2.
The last full line service on the Mandurah line will depart Perth at 8.08pm and Mandurah at 7.27pm.
A train replacement bus, Route 909, will run on the Mandurah line while trains are cancelled.
Transperth advised passengers to allow extra travelling time and reminded commuters that replacement buses may not connect with timetabled bus and train services.
They also reminded passengers that surfboards and bicycles are not allowed on Transperth buses, including train replacement services.
Trains will resume with the start of timetabled services the following mornings.
