That's nonsense comment. who runs the service? who owns the railcars? who controls the pricing? Who regulates the terms of service?
In fact, Fed.gov control of passenger rail, run on privately held freight tracks, creates a situation WORSE than total monopoly.

The owners still have to give permission for trains to pass
