Buses replace trains to Seymour, beyond
Buses will run between Southern Cross Station, Seymour and Shepparton due to signalling works from September 9 to 19.
Works to complete level crossing upgrades between Donnybrook and Shepparton will also be under way during that time.
A temporary coach replacement timetable will be in place, with both express and stopping-all-stations services.
It is recommended passengers allow an extra hour for their journeys.
