The trains are operating on Perth's suburban rail network and entered service on the Yanchep and Mandurah lines on 8 April 2024.

In April 2018, the Public Transport Authority called for expressions of interest to build 41 6-carriage electric multiple units.

Notable features of the new trains include a mixture of high back seats and bench seating, graphical passenger information displays (that are used the same as its predecessors in service), USB ports and hard-worn flooring instead of the carpet-laid floors of previous trains.

[12][13][14] The first train was revealed on 14 August 2022, with twelve months of testing along the Joondalup and Mandurah lines set to occur before they are put in passenger service.

A commemorative "first journey" occurred the day before on 7 April, with tickets to that open to the public via a lottery.
