I like to think about trains as well. I was never a fan of flying even though I've soloed a Cessna but didn't get my license.
When I was 19 in St. Petersburg I caught a train to Baltimore at this station on Seaboard Coastline. I worked that summer for a cousin who had opened the first Sub Shop in Ocean City Maryland on the Boardwalk, Billy's Famous Subs. That location is no longer, but there a Billy's Subs on 140th St in OC.
Seaboard Coastline and Atlantic Coastline (ACL) merged soon after my trip and this station was closed. It was very modern and nice, all brick and glass. Today it's the second photo below, the building still stands and has been expanded for a lumber business.
I caught the Autotrain from Sanford to Arlington, VA and back 3 times since I moved to TV. It's a neat ride and you have your car with you when you arrive. Takes about 19 hours, depart Sanford at 4pm and arrive in DC suburbs about 9am. At the exact time a train is departing Virginia and arrives in Sanford the next day and it's all repeated. Summertime is the best rates. Paid $900 each way in April, and paid only $375 each way in August.
The train station in Sanford and Arlington are identical, so that makes it easier to know your way around. They are as modern as most airports, which really surprised me.
Cars being loaded, never had a scratch on my car and they photo your car before and after. They pack them in on two levels.
The train cabins are very spacious, not cramped like an airline. We always took the last two seats so we could recline and not worry about the people behind us, there was wall about 2' in back. I think the seats were number 42 and 43. What I also like is the trains are double-decker, so you're very high up and see great. If you like a little more room or to sleep, they have sleepers downstairs for about $400 more. It's really a seat that folds flat and a curtain goes around you, I didn't think it was worth it. I sleep in my seat without much problem. Before your trip go to Walmart and buy a small pillow for $4 and a small blanket for $4, they have them on the train but more expensive.
Dining Car, If you're only 1 or 2 people they will seat strangers together. Once we had a young girl college student from DC going to UCF in Orlando. Normally you never have a conversation with a 20 year old, you learn a lot. Another time was fellow from Florida going to north for a NRA (National Rife Assoc) and he was a high level officer/speaker. That was also interesting since I'm not into hunting.
BTW, when I got out of Army in '72 my first job was a switchman with Southern Railroad in Savannah Georgia. I only lasted 30 days, it really wasn't what I wanted, but was interesting. I was on a waiting list for a federal job, so I moved on.
