What is the longest train trip you have experienced?(both)

@windinhishair Very relaxing. Plenty of time to read, meet passengers etc.
Some great scenery.
Highlight crossing the Nullabor is spotting a tree in the distance or Red Kangaroos chasing the train.
If one is easily bored then this trip is not for them.

@Gusman Sounds awesome. I've never traveled across the desert by train, though I have done quite a bit of hiking in the American desert. You can spot a single tree by a spring miles away and spend a whole morning or afternoon just hiking to it.

@windinhishair Our countries are so huge.
Thousands of Kms to get where one wants to go.

@Gusman I'm always amazed that you can still go places where very few people go, and get to them pretty easily. I hiked into a valley in West Texas in November once, and I was the first person to go there that year. I've hiked 40 miles on trails without seeing another human being. Solitude is there for those who seek it out. And even on the train, just seeing those areas is soothing.

@windinhishair Agreed.
I am in Western Australia, and I often go out into the countryside and there is no one around.
I go to out of the way places, not tourist spots.

@Gusman Those are the best places. I often find signs of native encampments from hundreds of years ago, as well as petroglyphs and pictographs on nearby rocks, in areas that are uninhabited. After a while, you can pick them out pretty easily by looking for the same things they would have looked for--a water source, shelter, and food resources.
