I would consider this has been accepted and implemented.
The secure radio is recertified on an annual basis by a radio technician and was last carried out in April 24.
Part of the preparation for use is a self-check of the radio by the operator. The trains are remotely controlled by Train Control and Wiri Operations. Therefor the radio must be operational to allow the authority to move to occur.

This recommendation is Under Consideration. Transdev Wellington will raise an engineering change request to implement the back-up radio communication check part of this recommendation and submit it to Metlink for approval and funding. As previously advised, Greater Wellington Rail Limited via Metlink, own the rolling stock and approve and fund any alterations. The main radio is used to call train control when departing yards; if this radio fails the train is unable to depart the yard and enter the network. There is also a self-test function on this radio which operates every time the train is powered up. The onboard radios are subject to annual certification by KiwiRail and are checked by Hyundai Rotem every 'B' check.
