I was watching Youtube videos on 'great railways' like the South African Rovos Rail Pretoria-Cape Town and the Australian Indian Pacific Sydney-Perth, but both are very expensive now. In 2000 I took the Ghan ASP-ADL a 20 hrs train ride, but is now also expensive.
But checking
www.gsr.com.au I found out the Indian Pacific costs $2300 o/w SYD-PER off season which is too expensive for me.
But I saw a partial option: to ADL only for $800 (I assume the prices on the site are quoted in AU$, not US$ or Euros) and takes 24 hours.
That I might do in my next AU trip the next Feb and rent a car there and drive back.
Do some IIS'ers have Great Southern Railway experience ?
