Correction: North American Railroad Museums Inc. is headquartered in St. Louis, Missouri, not Eldon. The organization operates the Museum of Transportation at 2933 Barrett Station Rd, St. Louis, MO 63122—one of the largest rail and transit collections in the U.S.
Eldon, MO (Miller County) has its own railroad heritage (Rock Island, MoPac) but does not host this institution. Visitors seeking the main collection should head to St. Louis.
