The Seymour and Shepparton lines will see a comprehensive implementation of the extreme heat schedule, while the Bendigo, Echuca, and Swan Hill lines will operate on a modified version of this timetable.
Travellers are advised to consult the V/Line website before their journey to check if their service is among those affected by the change.
For those planning to travel, an extreme heat timetable is available for download on the V/Line website, or a physical copy can be obtained at any staffed station upon request.
Commuters are also reminded to factor in additional travel time to accommodate the slower speeds.
Extreme heat protocols, including speed restrictions, are triggered once temperatures reach 36°C.
These measures are crucial for reducing the risk of train and track faults and ensuring the safety of passengers.
As a result, travel times may be slightly longer due to the reduced speed of trains under these conditions.
To further assist passengers during the heatwave, V/Line trains will be equipped with drinking water, and passengers are encouraged to carry bottled water and dress in lightweight clothing to stay cool.
