Major works will take place on the Sunbury train line as part of a five-day around the clock construction blitz.
The blitz between September 3 and 8 is the latest work as part of the Sunbury line upgrade, which is set for completion in 2023.
Crews will use this period to install signalling, communications and power infrastructure along sections of the line, power upgrades at the Tottenham substation and platform improvements at Middle Footscray, West Footscray and Sunshine stations.
Work will also be completed on upgrading overhead line structures at the Metro Tunnel’s western entrance in Kensington.
During this time buses will replace trains on the line between North Melbourne, Sunshine and Sunbury. Trains will resume on September 8.
From Sunday through to Tuesday, buses will extend to Sunbury after 8.30pm each night.
Coaches will also replace trains on the Bendigo, Ballarat, Geelong and Warrnambool lines on September 4 and 5.
Transport Infrastructure Minister Jacinta Allan said these upgrades were vital.
“We’re not wasting a moment delivering these vital upgrades to the Sunbury line, which will enable bigger, more modern trains to run on the line, giving passengers a better public transport journey,” she said.
“These upgrades will benefit commuters, road users and residents – supporting the needs of the growing communities in the west.”
As part of the upgrade, works to remove the Gap Road level crossing in Sunbury started last month.
Work on the commuter carpark upgrade in Sunbury are also a step closer, with the construction tender to open soon.
