From the Vault - The Great South Pacific Express over the Mountains - now in HiDef and Widescreen 

On 26 December, Boxing Day, 1999 the Great South Pacific had a rare run across the Blue Mountains as part of its run to Melbourne via Parkes. We followed the train from Emu Heights to Wallerawang.
It was a joint venture between Queensland Rail and Orient Express targeted at the luxury rail tour market.
It began running in April 1999 but ceased only four years later in June 2003.
As such its running predated the wide scale adoption of High Definition Widescreen cameras, and I'm unaware of any coverage of it in this format.
This video was originally shot in standard definition 4 x 4 format but has been upscaled and reformatted to widescreen.
