Forrestfield-Airport Link tunnel boring machine arrives in Perth

Key components of a 600-tonne tunnel boring machine have been delivered to the future Forrestfield Station, marking a major milestone in the delivery of the $1.86 billion Forrestfield-Airport Link.

The $20 million machine is one of two TBMs which will each dig eight kilometres of seven-metre diameter tunnels - including under Perth Airport and the Swan River.  

The highly specialised machine, one of only nine of its kind in the world, was manufactured by German company Herrenknecht.  It spent nine months in China for initial assembly and testing, and arrived at Henderson last week.

The TBM will be craned into the dive structure at Forrestfield, and in July 2017 will begin its two-year journey underground to Bayswater where the rail line will spur off the Midland Line. 

The video of the heaviest components of the TBM, the 74-tonne cutter-head and 164-tonne front shield (each seven metres in diameter), being delivered is available below:
