short: expensive and at least for the “Alice Springs => Darwin” part not really worth it. Problem is that you mainly travel at night (departure 18:00) – and don’t really see a lot… At 8am you arrive in Kathrine (where I did the “Gorge tour” which was nice!) and then it’s just a couple more hours to Darwin…

Wouldn’t recommend this train (Andes Explorer in Peru is MUUUUCH better)
