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. Early works on the duplication began in June 2016, with major construction started in March 2017. The duplication of the single-track section was completed in May 2018. 35 new and extended weekly train services between Eltham and the city loop took into effect on 26 August 2018. In May 2019, second stage of track duplication on line was announced. That includes adding second track between Greensborough and Eltham, and between Diamond Creek and Wattle Glen. Greensborough and Montmorency stations will be rebuilt. Eltham Trestle Bridge will be retained, due to its heritage status. Major works started in late 2020. A two week closure saw the raising of a new Plenty River rail bridge as well as other works, with the duplication now expected to be complete by mid-2023.
