Station work takes flight
WORK has begun on building the train station at Perth Airport as part of the rail tunnel from Forrestfield to Bayswater.
Diaphragm walls were completed recently for the station box.
“Excavation has commenced to remove soil from within the box and this will be ongoing for the next six months,” a newsletter on the Forrestfield-Airport rail link said.
“When excavation is complete, the station’s concrete base will be poured to seal the structure. Construction of the station box must be complete before the arrival of tunnel boring machine Grace in 2018.”
The borer, named after a local schoolgirl undergoing treatment for leukaemia, recently started tunnelling from the future Forrestfield station site in High Wycombe.
Equipment used to build the diaphragm walls at the airport will now move to the Belmont station construction site to repeat the process for its underground station box.
The Forrestfield-Perth Airport tunnel will go under the Swan River, Guildford Road and the airport before linking to the Midland line at Bayswater.
Construction started at the Perth Airport station site.
