Metro Tunnel

Construction on the Mernda line

Coronavirus and Victoria’s Big Build

Work is continuing safely on the Metro Tunnel Project as part of Victoria's Big Build. The health and safety of our workforce and community remains our top priority. COVIDsafe Plans are in place on all project sites across Victoria. Learn more.

Next-generation High Capacity Signalling (HCS) technology will be installed in the Metro Tunnel to deliver more trains during peak periods.

Testing

Before it is rolled out on the Cranbourne, Pakenham and Sunbury lines and in the Metro Tunnel, the new technology is being put through months of rigorous testing on a 4.5km section of track on the Mernda line, between Epping and South Morang stations.

This test site is helping us fine tune the operation of the system for use in Melbourne. The Mernda line was chosen because it does not share tracks with regional or freight services and has fewer timetabled night services than other lines.

What will testing involve?

Two test trains are being put through hundreds of scenarios to make sure the integration of the new technology, the existing signalling system and the train is functioning as expected.

We expect approximately 500 hours of track time will be required to perform these testing activities. These hours will be spread out across 2020 and 2021 to allow time in between testing for any modifications required.
