Work has started on the duplication of the Ballarat railway line between Deer Park and Melton.
Construction works have been brought forward to coincide with the building of the new Caroline Springs station, on the corner of Christies Road, near the Western Freeway.
The first section of the duplicated line, a one-kilometre section between Christies Road and the new station, is set to open early next year.
Works to duplicate the rest of the line between Deer Park and Melton are expected to begin next year.
Public Transport Minister Jacinta Allan said the “transformation” of the Ballarat corridor would deliver more frequent and reliable train services.
“Over the next few years we’ll duplicate the track, build new passing loops and upgrade stations to make it easier to get to work, school and appointments, and home safer and sooner at the end of the day,” Ms Allan said.
Three extra crossing loops will also be built at Bacchus Marsh, Ballan and Bungaree as part of the $518 million project.
New stabling facilities will be built at Melton and Rowsley to house extra train carriages, and a second platform will be built at Bacchus Marsh and Ballan stations.
The existing platforms at Rockbank stations will also be extended and a sealed carpark built on the south-side of the station.
Melton MP Don Nardella said the duplication of the railway line between Deer Park and Melton “paved” the way for the future electrification of the line.
“Duplicating the Ballarat line to Melton has been talked about for decades. The time for talk is over, work is under way – we’re getting it done,” Mr Nardella said.
