Price is not even the issue for me, it’s availability. I tried to book a ticket from Zurich to London for December. There are apparently not connections available anymore. I would gladly pay more than if I would be taking a plane, just give me the option…

There is Europe problem with integrated universal ticket system. There is lots of lobbing against it mainly from France, Italy, Spain. Then there would be some accountability for late trains, connections made… They just don’t want to do it.

More than accountability is likely prices. Train in Italy is much more expensive than switzerland or Germany. A single ticket would force them to lower prices
