SA accelerates towards zero-emission public transport

30 Jul 2023

The State Government is testing hybrid trains, hydrogen buses and a full-battery electric bus in preparation for a cleaner, greener future.

The testing of a prototype hybrid-diesel railcar is going well. The two-car train is the first of 44 diesel railcars expected to be fitted with the hybrid system to service the Outer Harbor, Grange, and Belair lines.

The system works by storing energy generated when the train brakes in an onboard battery and converting it into electrical energy to power normal train operations.


The first hybrid-diesel train is expected to be introduced into service in coming weeks, with another 44 upgraded trains planned to follow by mid-2024. Once all are in service, Adelaide Metro’s CO2 emissions will be reduced by 2,400 tonnes per year.

Two Foton Hydrogen Fuel Cells buses will soon undergo testing by our operator Torrens Transit, together with Foton Mobility, BOC, and H2H Energy. Following successful testing the buses will service routes across Adelaide as part of a two-year trial.

Hydrogen fuel carries significantly more energy than the equivalent weight of batteries. The State Government will also consider hydrogen for powering trains on the Belair, Outer Harbor lines and Grange and Port Dock connections.

The State’s first full battery electric bus is currently undergoing testing. A further five full-battery electric buses are on order, pending trial results. As well as being better for the environment, full battery electric buses offer passengers more space, comfort, and a quieter ride.
