Lufthansa cancelled our flights a few hours before departure and suggested via automated mail to instead take a train. From Hamburg to Venice.
That got me interested, but it takes about 15 hours to get there. On the other hand it's just 1200 km.
I wish we had a European high-speed train backbone, connecting all the big cities or similar. I would use it, even if the travel times would be twice as long and the prices twice as much as flying.
