Founded in 1944 but only now getting the attention it deserves with newly expanded grounds, this unique museum "houses one of the largest and best collections of transportation vehicles in the world" (according to the Smithsonian). Certainly, with more than 70 locomotives, the museum boasts one of the most complete collections of American rail power anywhere, including an 1858 wood-burning locomotive, a Big Boy (the world's largest steam locomotive), and a 1920s Pullman sleeping car. Automobiles on display range from a 1915 Ford Model T to Bobby Darin's 1960 dream car. Other highlights include a miniature passenger train and a trolley circulating the museum's 129 acres. Allot at least 2 hours to explore.
