In March 2011 Bombardier Transportation was awarded a contract to build 22 three-carriage trains for the Adelaide rail network that was in the process of being electrified.[2][3][4]

The design uses a similar shell to that of the V/Line VLocity diesel multiple units first introduced in 2004. The first was delivered in July 2013 entering service on 23 February 2014.[5][6][7][8][9] The last was completed in October 2015.[10][11] They currently operate services on the Seaford and Tonsley lines.[12]

When they were ordered it was proposed the Gawler line would be electrified, which would allow them to access Adelaide Metro's Dry Creek depot. However, before they were delivered, this project was cancelled. Whilst light maintenance is performed at their primary stabling point at Seaford, heavy maintenance needs to occur at Dry Creek, with each being hauled by a pair of 3000 class railcars from Adelaide station when required. When the Gawler Line is electrified to Salisbury in 2021, this will cease.[13] In June 2019 a further 12 train sets were ordered and are due to be delivered in mid-2020.[14]


The sets primarily operate on the Seaford and Tonsley lines, as well as the Showground Shuttle services between Adelaide and Goodwood during the Royal Adelaide Show. Two sets are coupled during major events, such as AFL matches, to make a six car set. This has caused problems with selected stations on the Seaford line that permit a maximum of five cars, including Mile End, Marion and Hove. To allow for these stations to be serviced despite the train length, the rear car doors are isolated to allow for safe alighting.
