This question is for the people lucky enough to experience American rail travel before Amtrak. In the 1960s, how common was it for the average American to use train as their mode of transportation? Were trains like the Super Chief or Broadway Limited actually household names? How about for the 1950s? Thanks for answering!
As one of the "lucky" ones, I can tell you that there was a huge difference between, say, the start of the 50's and the end of the 60's. The two biggest nails in the coffin during those two decades had to be Eisenhower's interstate highway system and the advent of commercial jetliners.
I still remember when major league baseball teams commonly rode the rails when there were only 16 teams, none further west than St. Louis. I recall seeing the Brooklyn Dodgers board a train for Cincinnati back in 1954 at Grand Central Terminal. I myself rode behind steam in the late 40's on trips from NYC to Lewiston, Maine changing at Portland. By the late 50's, it was all diesel and we had to go from South Station to North Station in Boston and change again in Portland.
Basically, to answer your question, in 1951 long-distance train travel was still viable, but by 1969 only the biggest name trains were left, and they were in their death throes.
