Canberra's light rail fleet has been retrofitted to operate with on-board energy storage systems.
02 July 2026
In brief:
- All light rail vehicles have been fitted with onboard energy storage systems to enable wire-free travel.
- The upgrade will enable battery-powered, wire-free travel between the Alinga Street and Commonwealth Park stops.
Canberra’s light rail fleet has received upgrades to enable wire-free travel.
Fourteen existing light rail vehicles have been retrofitted with on-board energy storage systems (OESS).
Each vehicle was taken out of service, fitted with batteries, and tested before returning to operations.
Extensive testing and trials have shown that the vehicles can operate safely and smoothly in all conditions.
Under Light Rail Stage 2A, vehicles will travel wire-free between the Alinga Street and Commonwealth Park stops.
Why upgrade to wire-free vehicles?
The new technology will reduce the impacts on sensitive national areas and maintain beautiful city views, by removing the need and space for lineside poles and wires.
There are also engineering benefits, such as a narrower track area, and less disruption to street space.
How does the new OESS work?
Each OESS has:
- batteries
- control electronics
- a thermal management system.
The thermal management system helps maintain optimum battery temperature in our city’s varied climate.
The OESS charges when the vehicles operate on wired sections of track.
It then uses that energy to power the vehicle on wire-free sections, where it will also capture energy through regenerative braking.
Delivered by a local workforce
The upgrades were delivered entirely within the ACT. This marks the first time the technology has been retrofit onto Light Rail Vehicles within Australia.
Building specialist skills in Canberra’s workforce strengthens our economy and boosts capability for future stages of Light Rail.
