V/Line trains on the Seymour and Shepparton lines will travel at a slower speed due to extreme heat on January 2.
A partial extreme heat timetable will be in place on the Bendigo, Echuca and Swan Hill lines.
Extreme heat speed restrictions are enforced when temperatures exceed 36ºC to reduce the likelihood of train and track faults and to keep passengers safe.
When the extreme heat timetable is in place, journey times may be extended by a few minutes as train speeds are reduced to 90km/h, with tracks at-risk of expanding.
A copy of the extreme heat timetable is available on the V/Line website or from staffed station.
Passengers are encouraged to allow extra time for their journeys.
There will be drinking water on board trains and passengers are also encouraged to travel with bottled water and wear cool clothing.
A full extreme heat timetable is in place today, January 1, on the Geelong, Warrnambool, Ballarat, Ararat, Albury, Maryborough, Seymour and Shepparton lines.
