B&O Railroad Station Museum

Welcoming its first passengers in 1830 and completed in 1831, this is the oldest surviving passenger train station in the US. A fun destination for kids and train buffs, the small museum spotlights the history of the depot, railroad china and the telegraph. Model trains loop past miniature towns in several rooms – don't miss the Baltimore to Ellicott City line in the freight house. There's a caboose to explore, too.
