I believe "D" is referring to items regarding the North Platte Canteen that met the troop trains during WWII as they stopped at the passenger station. Unfortunately, the station is no longer there, but there is a memorial at the site with the commemorative plaques to which he refers.
Bob Greene's book is about the famous canteen.
The Lincoln County Historical Museum has a special, permanent display of photos, documents, and artifacts of the Canteen. It's really not at the fairgrounds, but is located across from the Buffalo Bill arena.
Yes, there are very few veterans of that time still with us today. An excellent documentary DVD, "The Canteen Spirit," does include on-camera comments by some of the people who were associated with the Canteen.
North Platte has other features of interest to rail fans as well: the railroad display in Cody Park that includes a U.P. Challenger steam locomotive, the Bailey railroad yard (the biggest classification yard in the world), and the Golden Spike Tower that overlooks the yard.
And incidentally, there is the outstanding 20th Century Veteran's Memorial at the North Platte Interstate 80 exit #177, that's well worth a leisurely visit.
