Catch 22. If you underinvest in rail, you end up with trains slower than bus, which makes them a bad option. If you actually invest in rail, you end up in a situation where the rail is faster than bus and has less externality on the environment
Worse: if you underinvest, you end up with an unreliable and cost-inefficient train service that becomes ever more difficult to support politically. Which is exactly what we're seeing in this thread, good news from Amtrak notwithstanding.
