Johnsonville Line
Slope stabilising work on the hillside above Wadestown has been completed in recent months. Significant tunnel upgrades and overhead line electrical equipment upgrades were carried out in 2021.
Current work involves regular maintenance and rail replacement work as part of keeping the network up-to-date and reliable.
Overhead line renewals
In 2021, we upgraded the overhead line electrical equipment all along the Johnsonville Line. A lot of this equipment, including wooden masts and wiring, dated back to the 1930s.
Installing the modern traction system included building foundations for the new steel poles, installing the new structures and running new wiring.
Tunnel track work
In 2021, we replaced the sleepers in all seven tunnels on the Johnsonville Line.
The work involved replacing around 1600 wooden sleepers with more resilient concrete ones in the tunnels, each of which is between 100m and 200m long.
