In 1980, I took a round trip on Amtrak from Los Angeles to Ann Arbor, Mich. The train was 14 hours late arriving and 12 hours late returning. Afterwards, I vowed that I would never again ride Amtrak, and I never have.
I went from Orlando to Washington for President Reagan's funeral, but it was 12 hours late and I missed the funeral. And they don't provide free snacks and meals for those hours either. I'm not a fan of Amtrak.
Amtrak would have cost as much as the plane trip, and taken as long as the Greyhound. I ended up driving.
I looked up the same trip: travel is now out of Mobile, AL, with a 58-HOUR journey. If I ever decide to visit NYC, I may take a trip from DC on Amtrak, but that's about it.
