About Australian Railroad Group (ARG) was an Australian rail freight operator. It began operations in Western Australia on 17 December 2000 following its purchase of the Westrail freight business. It was purchased by QR National in June 2006. The main commodities hauled by ARG included grain, mineral sands, alumina, bauxite, coal, woodchips, quartz, nickel and iron ore around Western Australia. In June 2011, it ceased trading as a separate brand, and became part of QR National which itself renamed to Aurizon Rolling stock A class (ex WAGR A class) & AB/1500 class (ex WAGR AB class) D/2350 class (ex WAGR D class) & DA/DAZ/1900 class (ex WAGR DA class) DB/DBZ/2300 class (ex WAGR DB class) P/2500 class (ex WAGR P class) S/3300 class (ex Westrail S class)
This sounds like a cool idea. Lots of freight operations are possible. Australian trains should be added to TSW4.
