If instead that money could used to revitalize that stretch, it could be much more useful. America rail went through each small town as it already existed and the track is too twisty to go very fast over a lot of the stretch.
And it's all so we can have trains that go from DC to Chicago in like 12 hours + 0-3 hours of delays. That route is unnecessary. A DC to Chicago flight is 1:45 hours and is cheap as fuck. Plus we have buses that use the highways.
Our rail sucks because we propping up useless routes.
But, yeah, from a utilitarian perspective I've never found inter-city Amtrak travel to make a lot of sense in the US outside of the Northeast (nor, in many cases, Europe for that matter).

Germany simply doesn't have that. The infrastructural implications are massive.
