Thing is, freight trains are a far better use of the track than passenger trains: the system is ideal for slow-moving bulk cargo that doesn't care if it has to sit on a siding for a week, not to mention that it's a much less damaging way of moving heavy material around than trucks. Passengers, meanwhile, want to go specific places at specific times, and that just does not coexist well with freight. Better for passengers to travel by air, private car, dedicated high-speed rail, and other systems focused on the job.
