So far family enjoyed taking it entry time we visited. Similar to ferry, but by train. Car drives onto the open train. Views are gorgeous. We were lucky not to have any major delays, just a short stop before arrival once.

Avoid. Heavy delays (especially when leaving the island). Absolute nightmare for travellers with a schedule.

Would give this 2 stars for the chaos at the entrance and exit (too much traffic leading to long queues), but the ride on the train was an experience not to forget.

Disorganized and slow. Instructions only once on a loud speaker in German. You get to sit in your car behind the exhaust of the train inhaling the lovely fumes the whole ride.
