Rail right-of-way (train tracks) are owned almost exclusively by freight transportation companies in the US that have no interest in passenger transport. The US passenger train service (Amtrak) is a government administrated corporation that must pay private corporations for the right to use their tracks. Neither the government nor the private corporations really gives a shit about Amtrak, so it pretty constantly gets minimal help from the government, and high prices from the private corps. Which makes service expensive and low quality outside of a few places where the government cares enough to actually pay.
