RE: Amtrak's high-speed rail vision for 2040: New York to Washington in 96 minutes
It'll work only if they follow the necessary specifications for high
speed rail without cutting corners.
High Speed Rail is basically a Limited Access Expressway for
trains. That means no road/rail same level crossings, either the
rail goes over the road or the road goes over the rail, they can
not meet - ever. It also means the rail line must be fenced the
entire length just like a limited access highway, worse you can't
have any animal crossings at grade, they too must cross over or
under the rail.
