There should be an affordable way to move private passenger cars over America's railroad infrustructure. If Amtrak was providing that, fine. But if Amtrak doesn't provide it I think someone should.
I've always believe Amtrak continues to exist to shield operators from liability that others can't afford. No other private railroad REALLY wants to deal with the liability issues that arise from accidents and incidents. If you notice, the companies that typically take on passenger operations are a multi-layered consortium of companies that have deep financial reserves. These reserves are typically shielded but they exist.
it is no wonder that private car operators would like to latch on to Amtrak. Do you think CSX will give them the same deal? I remember NJT wanted to explore operations to Allentown or somewhere deep into NS. I'm paraphrasing the story, but NS basically told them "We welcome the thought, however don't count on the Amtrak formula. You will pay and you will be responsible for everything and anything that happens to your train and our property." The one quote I remember is "Don't assume our assets are readily available or come for free."
After that, NJT didn't even operate the inspection train!
