QR decided that the existing load bank, which had been in service since 1964, needed to be replaced. In a state of disrepair, its continued use was considered to be unsafe. Originally manufactured with the capability of incrementing load in 24 steps, its condition had not allowed the changing of steps for quite some time. QR determined that the new load bank should be controlled by the PLC/SCADA system incorporated within the load box control consoles. The original 24 steps could be condensed to 10 steps. In view of potential future overhauls of higher classes of Diesel-Electric Locomotives, the proposed upgrading had to have the capability to test 2800 and 4000 class. With this in mind, QR’s engineers sought the assistance of Chase Power Pty Ltd to write a functional design specification for the proposed new equipment. Chase Power specialise in providing engineered solutions and power quality equipment to their customers throughout Australia, New Zealand and the Pacific region. With the specification for a replacement load bank written, QR released the tender worldwide. Whilst companies from the UK and Europe were keen to offer their resistor expertise, only Chase Power were able to offer the turn-key solution QR required. Chase Power were contracted to design, supply, install and commission the new 2500V, 4000A DC Load bank, Switchboard and PLC programming, and to train the QR team in its operation. They teamed with local sub-contractors to deliver the specialised equipment which was designed and built in Brisbane, Australia.
