Underground stations evacuated
Perth Underground and Esplanade Stations were evacuated this morning when clouds of foul-smelling smoke rolled through the underground stations.
As a result, trains on the Mandurah and Joondalup lines were halted briefly.
The alarm was raised around 9.50am.
Two Mandurah trains which were stranded near the Narrows Bridge were allowed to come into Esplanade Station, from where the passengers were evacuated.
Services on the Joondalup Line resumed after about 20 minutes, with trains running into and out of Perth Station. On the Mandurah Line, trains coming up from the south are turning at Cockburn Central, and replacement buses are operating between Cockburn and Perth.
FESA is at the scene but, at this stage, the source of the smoke is not known.
