V/Line chief executive Will Tieppo said on days forecast to be 36°C or above, speed restrictions were put in place to ensure passengers and staff were safe while travelling on the network.
“Safety is our top priority and on really hot days steel tracks can expand in the heat, which is why trains may run at slower speeds, or are replaced by coaches when necessary,” Mr Tieppo said.
“Passengers can plan their trip with confidence by downloading extreme heat timetables from the V/Line website.”
V/Line closely monitors weather conditions during the warmer months to determine when extreme heat timetables will be activated.
On extreme heat days, extra crews will be on standby to manage any issues and ensure there are minimal disruptions to passengers as they travel.
No V/Line train, scheduled coach, or replacement coach services will operate in a fire district while a catastrophic fire danger rating is in place for that district.
While heat can affect services across the entire V/Line network, in northern parts of the state, extreme heat timetables are likely to be more common with higher temperatures over summer.
Passengers can download a copy of the extreme heat timetable for their corridor at vline.com.au
On days when extreme temperatures are forecast, passengers are encouraged to visit the V/Line website, app and X (formerly known as Twitter) feed.
Passengers can also speak with V/Line staff at stations or onboard trains for information.
