The 3000 class and 3100 class are a class of diesel railcars that operate on the Adelaide rail network. Built by Comeng and Clyde Engineering between 1987 and 1996, they entered service under the State Transport Authority before later being operated by TransAdelaide and Adelaide Metro. Trains are typically coupled as multiple units, though the 3000 class are also able to run as single units when needed. In total, 70 railcars were built and are expected to be retired between 2030 and 2032. ^[2]

The fleet underwent 3 major refurbishments. The first, an exterior refurbishment, was carried out between 2000 and 2010. The second, a life extension project was completed between 2018 and 2020, aimed to extend the trains' lifespan. A third and final refurbishment, a hybrid conversion is being carried out on 45 of the 70 railcars to reduce fuel consumption on the fleet.
