Emergency exit points

Works update

After waterproofing was completed, the permanent concrete between the tunnels and the emergency egress shaft (EES) near Abernethy Road has been poured and focus will now shift to construction of the staircase, lift shaft and ancillary building.

At the Airport West EES construction of the base slab is scheduled to commence in September, followed by trenching works to allow installation of services. Once completed, the EES will also be connected to the tunnels.

After completing the capping beam for the Wright Crescent EES in Bayswater, excavation of the 2500 tonnes of soil is underway within the 9m diameter shaft. It will take approximately eight weeks to complete the excavation and during this time there will be 10 to 20 truck movements each day.

Works will be undertaken Monday to Saturday from 7am to 7pm. Once all the soil is excavated from the shaft, the base slab will be poured to seal the underground structure.

Cross passages and emergency ergress shafts

The route for the Forrestfield-Airport Link includes 8km of twin-bored tunnels, with safe entry and exit points via underground stations at Redcliffe and Airport Central. Trains will enter the underground rail line via tunnel portals at Bayswater and Forrestfield.

Given the length of the tunnels, additional infrastructure is required between the stations to allow safe egress to the ground level in the event of an emergency, and access to the tunnels for maintenance. As such, 12 cross passages and three emergency egress shafts will be built along the alignment.

Cross passages

The cross passages are located at numerous points along the route to provide a connection between the tunnels. In the unlikely event of an emergency, passengers will be able to exit the train and use the tunnel walkways to locate the nearest cross passage. They will then be able to enter the adjacent tunnel safely and exit through the nearest emergency egress shaft, station or dive structure.

Cross passages are constructed using the jet grouting process, a construction technique used to improve ground conditions and stabilise soils in preparation for tunnelling works.

Emergency egress shafts

Emergency egress shafts provide emergency exit points for passengers along the tunnel alignment. In the event of an incident, commuters will access the emergency egress shafts using the cross passages and walkways within the tunnel. They will then be able to use either the stairs or the lift contained within the emergency egress shaft to reach ground level emergency muster point. 

Emergency egress shafts will be built in three locations along the alignment:

  • Wright Crescent, Bayswater
  • Woods Road, within the Terminal 3 & Terminal 4 Precinct (Airport West)
  • Abernethy Road, Forrestfield
