Amtrak is a joke,

Yes.

It’s shameful we don’t have a modern high speed rail network in the US.

Again, true.

and Biden should have done more about it when he had the chance.

Yeah, I’m in agreement with @NOT_RICK in that Biden was stymied by popular opinion and richbitch protest to not spend on things like infrastructure because he was too busy dumping money into the disaster-du-jour caused by chronic insufficient investment in infrastructure and healthcare … again, prevented by richbitch politicos reframing everything as "taking money out of the hands of the middle class for some boondoggle like heathcare. “Who in Louisiana or North Dakota even USES I-5, anyway?” and similar bad-faith arguments.
