Don't really travel by rail much other than the occasional subway/Metro North trip, but my most "memorable" one was probably taking Amtrak from Washington DC up to New Haven, CT. We were on a school trip and had to delay going back by a day due to a large snowstorm back home. Weather in Washington DC was much better than back home, even sunny. Next day we take the train, and the further North we went, the more and more snow was on the ground until we got back and saw 2 feet of snow.
