The Arctic – A railway line operating in the Arctic required centre liners that could function in sub-zero temperatures while carrying fully-loaded iron-ore wagons. This combination of high load and freezing conditions tended to result in rapid wear to traditional liners. Hilube 10 replacements were opted for, as the material can withstand temperatures up to -40˚C. Easy machining and fitting and smooth running bogies on straight and curved tracks were the result.
