When did the Australian rail freight operator, whose main commodities included Aluminium oxide, become part of QR National?
Aluminium oxide Aluminium oxide (British English) or aluminum oxide (American English) is a chemical compound of aluminium and oxygen with the chemical formula Al O . It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium(III) oxide. It is commonly called alumina, and may also be called aloxide, aloxite, or alundum depending on particular forms or applications. It occurs naturally in its crystalline polymorphic phase α-AlO as the mineral corundum, varieties of which form the precious gemstones ruby and sapphire. AlO is significant in its use to produce aluminium metal, as an abrasive owing to its hardness, and as a refractory material owing to its high melting point.
Dominion Timber and Minerals Railway The Dominion Timber and Minerals Railway was a private standard-gauge railroad that operated in the Laurentian Mountains of Southwestern Quebec, Canada from 1916 to 1981. Owned by Canadian Refractories Limited, the railway's 20km mainline stretched from CRL's magnesite mine in Kilmar, through an extremely rugged mountain route to its final teminus at Marelan. Originally a narrow-gauge railway from 1916 to 1933, the Dominion Timber and Minerals Railway expanded to include a 65-ton locomotive and several freight cars.
