So in most Western European countries I think that limit is actually more like 1000km, or if it includes crossing France even more than that, or if you’re not close to the airport too. Beyond about 7 hours of train, flying starts to be faster and more convenient, most people around here find, but you can get quite far with a train in that time. I appreciate the current situation in the US isn’t the same and it would cost money to upgrade the network, but I think the rest of the world does show that it’s actually worthwhile.
