Not really into travelogues like this (and this was no exception), but I will say I love me an Amtrak trip.
In 2015, I rode from Portland, OR to Boston, MA. Took 5 days, through Sacramento, Chicago, and DC. I was traveling alone so every evening in the dining car I was seated across from a different Giant Train Nerd and got to learn about the engine on the current train, the type of track we were riding on, who owns or owned the land, really interesting stuff.
Both before and after that I've taken trains between Boston and NYC several times, and taken the Auto Train (which carries your car!) between DC and Florida.
Every trip makes me wish I had the leisure time and the country had the infrastructure such that I could avoid even more plane travel and take a train instead.
So I definitely get the urge to write a meandering travelogue about just such a trip. But as you can see, the same information fits just fine into a reasonably-sized internet comment.
