Cummins is installing them in the existing trains of the VLocity fleet, which the state-owned rail operator V/Line uses for regional transport in the Melbourne metropolitan area. 

The CPU boards monitor the traction motors, record operating data, and transmit it to the train control system. Since the previous boards have reached the end of their service life, the new ones serve as a seamless replacement. They are developed and manufactured by Selectron, while duagon, through its Australian branch, handles all shipping logistics and acts as the sales and contact point for the customer on site.
