The only national passenger train service I know of is Amtrak, which shares its tracks with freight carriers. So the current infrastructure isn’t designed for high-speed rail and freight carriers usually get priority.
Also, The US is really big, so everything isn’t a short train ride away from everything else. If I wanted to visit the Grand Canyon from where I live, it’s over 2,000 miles away. That’s 30 hours of driving just by car.
Because that bench was deliberately designed to discourage people from sitting there. To make people miserable. So which political party LOVES to be pointlessly cruel?
