Having grown up in New York City, I used to ride subways all the time. My family all lived fairly close back then, so we had no need for extensive travel for visiting.
Vacations were all motor trips within a hundred mile or so radius usually. So I had little exposure to 'real' railway travel.
I did get a brief glimpse when meeting family visiting from Massachusetts at Grand Central Terminal. And when taking our grandfather to Penn Station, on his winter vacation in Florida. What wonderful temples of transportation those were.
My first solo long distance travel was by bus when I was 8 and then 12 years old (those were different times). Main reason was that it was a one-seat ride between New York and Worcester, Ma. Train would have required a change in either Springfield or New London.
Fast forward to 1966. After having flown in to Chanute AFB at Rantoul, Il, and spent a couple of weeks at Tech School, it was time for first weekend pass. Since I was familiar with bus travel, I selected Greyhound as my ride to Chicago. I boarded the old Scenicruiser, and it was a local, taking 4 hours and 20 minutes to reach the underground Loop terminal. The next time I went with some buddies, who insisted we ride the train. The Illinois Central Louisiane, an all day local picked us up on time at 4:12 PM. I settled into my seat. I was reading some literature, and turned to my companion asking when we were leaving. He looked at me quizzically and pointed toward the window. I looked out and couldn't believe what I was seeing--we were rolling along at about 30mph and accelerating. The start was so smooth and imperceptible as compared to the subway trains I was used to that I didn't even feel it. We were soon rolling along the Mainline of Mid-America at about 90mph. Just as smooth as the starts, were the station stops at Paxton, Kankakee, and Homewood. We rolled into the lakefront Central Station in a bit over two hours. Train was used from then on.
Around four years later, a friend introduced me to railfanning and luxury rail travel. We had flown to Chicago on a TWA 707, and boarded the combined Burlington Afternoon Twin Cities Zephyr/Great Northern Empire Builder/Northern Pacific North Coast Limited. What an impressive train with leg-rest chair cars, Pullman sleepers, slumbercoaches, dining cars, coffee shops, lounge cars, and domes, domes, domes galore. Vista Domes, Great Domes, Lounge in the Sky.....everything! We took that train to Minneapolis, took a Jefferson PD4903 bus down to Osceola, and caught the California Zephyr back to Chicago. We then flew home on a UAL DC-8-61.
That trip really got me hooked.
