Tunnel Boring Machines from Sydney Metro arrive to build the Cross River Rail

Two Tunnel Boring Machines (TBMs) have arrived in Queensland, to be assembled and deployed to dig out the Cross River Rail tunnels.

Tunnel construction is expected to start on the project in early 2021.

Premier Annastacia Palaszczuk said it was another significant milestone in the progress of this transformational project.

“We know that to continue rebuilding Queensland’s economy, we must forge ahead with job-creating infrastructure like Cross River Rail,” Palaszczuk said.

“Both of these TBMs weigh 1350 tonnes which is about as heavy as four Boeing 747s.”

She says they are the same machines that dug the Sydney Metro. Now they’ll get a full refit and refurbishment at Herrenknecht’s north-side facility, to prepare them to dig Brisbane’s first underground.

“More than a dozen people have started working on the refit of the Cross River Rail TBMs, and that will increase to up to 35 people during peak activity – local jobs at a local factory.”

“We’re also ready to give the machines new names for their new task.”

State Development Minister Kate Jones said the TBMs will be launched from the Woolloongabba Station site and will each dig a tunnel under the Brisbane River to the Albert Street Station.

They will then continue to the new Roma Street Station before emerging at the project’s northern portal at Normanby.

Currently 16 workers are refitting the TBM’s at Herrenknecht and an additonal 15-20 wrokers are expected to start working on the TBM’s over the next nine months.
