I stumbled across a YouTube channel showing primarily freight trains on the New South Wales network. The channel shows lineside views at various stations and some shot from parallel roads or overbridges. Away from the Iron Ore lines in the Pilbara the tracks are owned by the various States, which also provide all the passenger services, except for Tourist trains like, The Indian Pacific, The Ghan, and The Great Southern, and The Overland, which are operated by a company called Journey Beyond Rail with their trains hauled by a freight company.
Outside of the coastal commuter belt the tracks arre managed and maintained by Australian Rail Track Corporation owned by the Federal Government. The major freight companies operating on the interstate network are
Pacific National
Aurizon
Qube
Specialized Container Transport
Southern Shorthaul Railroad
In addition you will see leased locomotives from the Australian equivilant of CEFX RailFirst Asset Management.
His channel is called South Coast Freight Australia
