I would be very interested to know which countries have 100% grade-separated crossings, especially if they're mostly flat, so they can't take advantage of terrain (and also aren't micronations).
For high speed rail, most countries with any real HSR infrastructure will have grade separation unless absolutely impossible for some reason. France, Japan, Spain.
Ah, that's why. It's because Brightline service isn't really high speed rail, and in countries where they do have real high speed rail, the infrastructure is built out to actually support it.
I was looking around at French rail service, and the true high speed rail is grade-separated, but the regional rail service still has grade crossings.
That makes sense. If you're actually running high speed rail that's actually high speed, grade separation is not really optional. A few wood barriers (that cars can drive around if the drivers are dumb enough) don't cut it when a train is going 350-400km/h.
On those tracks, people are used to very slow cargo trains. That also means that if you have to wait, it can be a very long time. Idiots may be tempted to go around because of the long wait, and there’s usually lots of time. Their whole lives, they e gotten away with this
Then a medium speed train comes through. They wouldn’t have had to wait. There’s no time to go through and still avoid. But the idiots don’t know that, despite the regular news for the last several years
