That would be my 'VR BG Wood' track (clean and rusty versions) It can be found on the Download Station under the username 'S301' (User ID 103475), which is my personal account.
Comes in a few versions, both clean and rusty, and broad gauge (5ft3in) and standard gauge versions.

That does depend on what you are modeling I agree that the 'USLW' and 'JR' tracks are fantastic, however as they aren't available in broad gauge, they won't work too well for a Victorian Railways layout
