The famous Baltimore & Ohio Railroad was founded on the site that now houses this museum, which contains more than 120 full-size locomotives and a great collection of railroad memorabilia, from dining-car china and artwork to lanterns and signals. The 1884 roundhouse (240 feet in diameter and 120 feet high) contains exhibits and historic objects. It adjoins one of the nation's first railroad stations. Train rides are available Wednesday through Sunday (weekends only
in January). TraxSide Snax serves food and drinks.
