>> Have you done the train Melbourne to Adelaide?
Yes, I did it in 2013 (2nd class), en route to catch the Ghan to Darwin. It was very ordinary (but I would do it again).
They had some rather peculiar practices, such as making the 50 or so passengers boarding in Melbourne queue up along the platform to be ticked off on the manifest before boarding the train. With only one crew member doing that, you can imagine how long it took to board. Then, we were all herded into one carriage, with another carriage left completely empty - I suppose for others boarding en route.
The train bumps, squeaks, rattles and lurches its way to Adelaide in 10.5 hours, but they had the endearing practice of giving us a little spiel about many towns we went through - including the (apparently famous!) sun moths at Nhill :-D They also pointed out features in the landscape, which was mostly brown grass plains or ploughed paddocks with scattered trees or scrub. We saw a few kangaroos.
The food is pre-packaged, so not great, and the bistro car quite uncomfortable to sit in, the seating consisting of high and low round stools with no back rest and small tables (more like glorified ledges) built into the wall, but I nevertheless spent a lot of the journey in there rather than in my seat, as you could sit face-on to the windows, and talk to other passengers more easily.
The train was too long for most platforms, so people getting off en route had to move to the front of the train to disembark. (The Melbourne-Sydney train only unlocks selected doors at most stations too, sometimes due to short platforms, other times just on a whim it seems!)
The Adelaide Terminal is not within cooee of the city centre, but there is a shuttle bus, or you can get a taxi into town.
The interior of the train was beige, which pretty much sums up the whole trip :-D In comparison with Switzerland, the whole experience was like being in a time warp!
>> Did you see the 3-hour SBS program on The Ghan? Mesmerising!
Yes, I did! It was great to relive it, and so unusual that there was no commentary. It was very well edited to keep it interesting.
PS We need an off-topic forum :-D
