The 2000/2100 class were a class of diesel railcars operated by Adelaide Metro. They were built by Comeng, Granville in 1979-1980.

The 2000/2100 class are self-propelled diesel railcars operated by Adelaide Metro on the Adelaide metropolitan rail network. The body shell design was based on the Budd SPV-2000, Metroliner and Amfleet cars but the 2000 class railcars have a slightly different curve to the Amfleet. The bodyshells were built by Comeng, Granville before they were railed to Adelaide for fitting out. They entered service in 1980. They acquired the nickname "Jumbos" due to the raised driving cab, similar to that of the Boeing 747. This raised cab was designed so that two passengers could sit at the front or rear window.

Twelve 2000 powercars and eighteen 2100 class trailer cars were built. The powercars were originally powered by V12 turbocharged MAN engines that have since been replaced by two turbocharged 6 cylinder Cummins engines under the floor driving a Voith hydraulic transmission. They usually operate in 2-car (power-trailer) or 3-car (trailer-power-trailer) configurations.

From 23 February 2014, these cars were no longer permitted to operate on the Belair and Seaford lines due to low clearances as a result of the electrification of these lines. After February 2015, they only operated on the Gawler, Outer Harbor and Grange lines, with 11 of the original 30 railcars still in service. The remaining fleet was retired in August 2015.
