Classing: MRL - Mineral Resources Limited: owner
The first 4 MRL's were originally the CRL class that were built in anticipation for an order. They sat around the UGL facility at Broadmeadow for may months until finally being painted into MRL colours and transported over the continent to Western Australia. MRL's 5 and 6 were the two final GWU's that were also built for an order that was never placed and had hung around for a long while.
