Adelaide Metro’s 3000 and 3100 Class Diesel Multiple Units were based on the design of the Melbourne Comeng suburban electric trains. A total of 70 cars entered service from 1987 to 1996. During 2023 and 2024, 70 cars were converted to diesel-hybrid technology. They were fitted with ABB lithium-ion batteries as part of an energy storage and recovery system. Kinetic energy generated during train braking is stored in the onboard battery, then converted into electrical energy when required to power train operation. Twenty cars were retired as they were no longer required following the electrification of part of the suburban network. The 3000/3100 Class are in service on the Belair, Outer Harbor and Grange Lines.
