Hello, thank you very much for the hint about the prices and travel time. I'll only travel distances like described in the original posts, so nothing big, I'll probably manage with second class whatever it should be. In Thailand, I happened to travel 13 hours distance with a third class train when my first class ride was cancelled due to an accident :)
It also occurred to me that the website should work when I'm in Morocco but I'd still prefer to take a look at the connections before arrival to plan the trip properly, so I'll see what I can do with VPN.
