I managed to make the last of all fifty in August, 2018. I began 2018 with only Hawaii, Oklahoma, and Michigan left. So I flew to Hawaii in March to get away from the snow and subzero temperatures here. And in August I flew to Oklahoma City, and took the Heartland Flyer to Fort Worth ( but not before taking in a doubleheader in Oklahoma City between the OKC Dodgers and Iowa Cubs the day prior), then took the Eagle to Chicago, transferred to the Wolverine, and went on to Dearborn, where I spent a day at Greenfield Village (and could have spent another day or two) before heading back to Chicago on the Wolverine and then taking the EB to Spokane. Of the four states not currently served by Amtrak, I have ridden the rails in two of them, as the focal point of my one trip to Alaska was riding the Alaska Railroad between Anchorage and Fairbanks, and while on a road trip to Mt. Rushmore in 2015 I took the Black Hills Central tourist train between Hill City and Keystone,SD. I'd like to be able to say I've ridden the rails in all 50 states. I'm not sure how to do that, especially in Wyoming. I don't have the luxury of getting time off at short notice when the CZ detours through Wyoming.
