Australian Railroad Group

ARG logo from 2002 until 2006

In 2000 the Australian Railroad Group was formed as a 50/50 joint venture between United States rail operator Genesee & Wyoming Inc and Australian rural services company Wesfarmers, to bid for the freight operator Westrail which was being sold by the Western Australian state government. Genesee & Wyoming already had an Australian presence, having purchased the South Australian freight operations of Australian National in November 1997 and rebranded the operation Australia Southern Railroad.[1][2][3]

In October 2000 Australian Railroad Group were announced as the successful bidder for Westrail with operations commencing on 17 December 2000. Under the deal 95 locomotives, 2,500 wagons, freight terminals and customer contracts were purchased with the infrastructure remaining in government ownership, and leased to ARG for 99 years.[4][5]

As part of the deal, the joint venture assumed ownership of Genesee & Wyoming's South Australian operation, Australian Southern Railroad.[4]

Initially trains in Western Australia operated under the Australia Western Railroad name, with AWR logos being applied to locomotives in the orange, black and yellow of Genesee & Wyoming. With ARG's involvement with the Asia Pacific Transport Consortium building the Alice Springs to Darwin line, resulting in some locomotives operating construction trains on the line receiving Australia Northern Railroad logos, it was decided to rebrand all ANR, ASR and AWR operations under the Australian Railroad Group banner from August 2002.[3]

In June 2006 the joint venture was dissolved with Wesfarmers selling its 50% share in the South Australian operations back to Genesee & Wyoming. The above rail operation in Western Australia was sold to QR National and the below the rail WestNet Rail infrastructure business to Babcock & Brown.[6][7][8]

In June 2011 it ceased trading as a separate brand, and became part of QR National.[9]

With the introduction of the ARG name and corporate colours, ARG began a gradual process of standardising the locomotive classification based on horsepower, with a progressive (and still incomplete) renumbering. As of February 2006 new letter classes will be used in conjunction with the new horsepower based numbering system (The Z on the end of some class letters refers to locomotives fitted with ZTR).
