In May 2016, Victorian State Government allocated the funding for duplication of 1.2-kilometre section between Heidelberg and Rosanna stations. Upgrade includes construction of second railway bridge over Burgundy Street in Heidelberg, second tunnel for Flinders Street-bound track under Darebin Street, next to the existing Hurstbridge-bound single-track tunnel and a new elevated Rosanna station. In conjunction with section duplication, two level crossings - at Grange Road in Alphington and Lower Plenty Road, next to Rosanna station, were separated as part of Level Crossing Removal Project.
