Think the staging is something like :
1. Sleeper replacement Maryborough - Mildura and other preparatory works . (Nearing completion) .
2. Upgrade re - open Maryborough - Ararat including new direct sg link at Ararat to the Maroona Line.
3. Move rail over Dunolly - Mildura ; all Mildura trains via Maroona and Gheringhap to Geelong and Melbourne on sg .
4. Standardize other North Western branches radiating from Dunolly.
5. Standardize / dual gauge South of Maryborough .
6.Remove broad gauge rail between Maryborough and Dunolly .
