All are different, all have their pros and contras.
It's up to you to make a choice.

Huh?

ditto . . . Why on earth?

(if you just wanted to save the info to read later you could always e-mail the thread to yourself)

So what exactly is the question? Which of them is the highest?

That's a list of the highest places of the Alps which can be reached by cog wheel railways, rope railways or gondolas.

8 of them are in Switzerland (all in the Canton of Valais, except Diavolezza in Graubuenden/Bernina), 4 in Italy (3 of them in the Aosta Valley area), 2 in France (Chamonix), 3 in Austria (North Tyrol).

But yes: what's the question?
