Doesn’t the Shinkansen and other HSR systems get rid of at grade road crossings? Yes, without people actually crossing in the tracks, you’ll get less deaths that way.
This seems like an awfully fanciful idea for anywhere but places with the most dense rail networks per sq km, at least if we're talking a full-scale refactor of existing infrastructure, in terms of financial, physical, logistics.
Is it not somewhat true that rail/freight companies have more authority over the land that their lines run through than the regions do? I may be talking out of my ass here, but I feel cities and provinces in Canada pretty much have to yield to CN or BNSF in some form or another; they operate their own police afaik. Railyards seem to be regarded as defacto permanent fixtures in terms of urban infrastructure.

It seems to be the contrary to me. In Japan or France (in the denser places of these countries, because they have plenty of low density areas) building a whole new dedicated rail network was (and still is, see the Bordeaux-Toulouse LGV project) a major undertaking because there's no way to avoid built-up areas. The high-speed lines go from city center to city center, and we're talking about Paris and Tokyo here.
The Shinkansen and TGV use dedicated rail networks, that are built from scratch and are still being expanded. TGV can use legacy lines as well at low speed (including at grade road crossings, although these have almost completely been replaced today) not sure about Shinkansen.
In contrast, it seems to me like it should be easier in the US to find space for cheaper bypasses, tunnels and bridges since it's less dense.
In what way is it fanciful? There's an extensive network of interstates in the US with nearly zero intersections. If it's viable for I-90 why isn't it viable for the equivalent rail line?
The US created a cross country rail network, basically by government fiat and investment, well before there was anyone out there to ride them.
Hell, a lot of towns with good rail access nowadays in the US only exist BECAUSE the rail line was built there.
It's hilarious how often "but density" is wheeled out to complain how we can't do trains when, not only did we use trains to create density, but the US has regions that are denser than Europe and could easily support comprehensive rail. The US is a place where people are unwilling to buy a car that can't go 300 miles on a whim. People used to take the trains for day long trips.
There is no excuse but political. We could talk about how expensive it is to build anything in the US but the US has always had massive pork in large projects and is so fucking rich that if we stopped giving free tax breaks to billionaires and maybe go a decade without having to artificially inflate our economy we could build the most expensive railroad network in the world with giant kickbacks included and STILL benefit and afford it.
We could financially justify not just removing grade crossings, but a literal maglev between DC and NYC (The city pair has higher GDP than Osaka and Tokyo, which is actually getting a maglev)
Don't know how it is in the US, but it's similar for cars, highways don't cross small routes either there's typically a (small) bridge involve (no need for viaduct).
Not only are most trains not Shinkansen, not even most trains in Japan are Shinkansen.
