It is a train tunnel. You have to drive the car on the train. It is very fast: the crossing lasts 35 min of which 20 min in the tunnel.

I'm very claustrophobic and have fear for heights (you call that 'vertigo'?). So, I don't like elevators, planes, etc.
But I've got no problem with tunnels!!
My wife Rita is not claustrophobic, but she doesn't like tunnels.
The photo was taken (inside the carriage) while riding through the tunnel.
