My parents in law travelled across the Nullabor on the Indian Pacific.Oh! I love the Ghan! I did the trip about 15 years ago. It's like the Orient Express (which I've also done) except through the Australian outback. Husband wants to try the Maharaja's Express through India. Luxury and curry - sign me up!
Unfortunately, my mother in law who was a very light sleeper, scored a bed right over the wheels.
Poor sleep pretty much soured the experience for her.
