Good morning Gents ((HUGS))
This is why I said I'd like a better schedule between the two states.
I took the train from DC to CA back in the 90s and loved the trip...BUT...it took a long time AND we had to layover in Chicago (the return home was worse).
As publius said, it's fun to travel by train if you are not in a hurry.
I just wish the train system had more direct non-(or minimal)-stop routes between cities, as I'd love to take more trips by train.
Amtrak uses Chicago. That's why most of their long distance trains begin and end in Chicago.
During layover time at Chicago Union Station, if it's warm enough, I'll walk around the Loop and get a meal. Once I rode the El to Evanston and back. I don't mind the layover.
The best part was sitting in my deluxe compartment in the sleeping car, reading or watching the scenery roll by. In the dining car, I got to meet real people. I've had meals with authors, historians, English vacationers, and spec-ops players from the military. For sleeping car (first class) passengers, the meals are free, and I only pay for the booze.
If you have the time and want to just relax and not worry about TSA gropers and state troopers, it's the way to go.
