Extreme Heat Transport Plan

Extreme Heat

South Australia can experience long periods of extreme heat which may impact upon the operation of our public transport services - particularly rail. The Department for Infrastructure and Transport’s Extreme Heat Rail Transport Plan provides guidelines for maintaining rail public transport services in times of extreme heat. 

When is the plan put in place?

Extreme heat is defined as two or more consecutive days with forecast 40 degree plus temperatures based on the Bureau of Meteorology website. This only applies when there are two or more consecutive weekdays of extreme heat forecast. Weekends will not be affected due to lower frequency of services.


The plan reduces frequency on selected afternoon peak train services and increases the length of the trains to maintain capacity and service. Trains may also operate at reduced speeds as a safety precaution.

While every attempt will be made to sustain these services, extreme conditions may impact other services based on assessment of the condition of the infrastructure and other operational and safety issues.

An assessment of tram services will be made following the morning peak on the affected day. Tram services may run at a reduced frequency or speed during the afternoon peak period if required. To reduce frequency, shuttle services may be suspended allowing full-line operations to continue.


The Adelaide Metro website will alert customers when the Extreme Heat Rail Transport Plan is in place, customer who have a My Metro account and have subscribed to alerts will be notified by SMS text message or via email. The Adelaide Metro Website will also display any changes to the timetable as well as updates on the status of the network.

Additional notifications are provided through social media and media outlets will be informed.

The Adelaide Metro InfoLine message-on-hold keeps our customers informed on any changes to the regular timetables. Customers can call 1300 311 108 for alternative travel options.

Adelaide Metro staff will be available at the Adelaide Railway Station from approximately 3:30pm to provide information from the Customer Service booth and within the station. Voice announcements in Adelaide Railway Station and at other key locations are provided at regular intervals to keep customers updated on platform details and departure times.
