Harding Siding, Robe River ore waggon 074 built by Nippon Sharyo Nihon in 1971 is one of a few waggons that runs permanently coupled to another waggon. Unlike the Hamersley Iron system married pairs, the Robe fleet each have their own brake system and are coupled by a length of round bar as the Cape Lambert dumper only dumps one waggon at a time.
