I saw in my former city a bus line get replaced by a train. It was infuriating. They tore up the roads and replaced the busses with trains which are worse in every imaginable way. They did this while also passing local laws which made it harder to operate scooter/bike rentals (bird scooters and the like).
But these politicians just think literal trains are the solution. Again, its' weird cargo cultism.
A legit high speed rail (300kph) line that went from Seattle to San Diego, or from Minneapolis to New Orleans would be great. It doesn't seem like anybody is even trying to do that.
