In the golden age of railway the WA government ran affordable holidays to show off the state's attractions, by Emma Wynne 18 February 2024:
"Fundamental to the reso tours was that the passengers would sleep on the train rather than a hotel or other accommodation."
A few trains are still operating, the Prospector to Kalgoorlie and the Australind to Bunbury, but there are no more sleeper cars and no more reso tours.
It seems reso tours were a thing elsewhere in the country too.
