Metro Tunnel

Construction on the Mernda line

We are doing our part to help reduce the risk of infection and slow the spread of coronavirus (COVID-19) in the Victorian community.

Before High Capacity Signalling is rolled out on the Cranbourne, Pakenham and Sunbury lines and in the Metro Tunnel, the new technology will be put through months of on-site testing and validation.

The health and safety of our workers and the community is our key priority as we continue to deliver the Metro Tunnel Project, as is supporting physical distancing measures in line with current health advice.

We have strict protocols in place to protect the safety of our construction workforce, including enhanced industrial cleaning arrangements, provision of personal protective equipment and measures to reduce staff contact, including staggered shifts.
