For those from Sydney, Auscision have released a ready to run HO Scale model of the XPT that runs in regional NSW and running to NSW, Queensland and Victoria.
Train originally sold as a 5 car set (2 powered power cars and 5 coaches with the option to addon an additional 2 cars) In my opinion, its really good to see a properly detailed train especially the XPT
