Long distance? You can’t even take the train to where you want to go anymore. I checked into taking the train from central NY State, to Indianapolis, Indiana, and there are no commuter trains that could get me there. There is no train that goes to the western part of the State. I specifically called and talked to someone in Amtrak’s ticket office, and they confirmed that there was no way I could get there by train. My father worked on the New York Central Railroad for over 50 years. He retired not long after they became Penn Central. If he were alive today, he’d be devastated to see what has been done to the rail system and the country. He came here from Holland at the age of 8 in 1912, was naturalized, and an FDR Democrat his whole life. He would not recognize the party today.
There are some private train services starting up, like Brightline in Florida.
The line that used to go across the south, from CA to FL, I think, stopped with Katrina. Never came back.
