Historic Site

Undoubtedly the most spectacular and best known of the museum’s buildings is the Roundhouse, which is a National Historic Landmark.

The Mt. Clare Station, also known as Mt. Clare Depot, is the oldest surviving building on the museum’s historic campus and is a National Historic Landmark.

The B&O’s Passenger Car Works, or Car Shops, consists of two buildings commonly referred to as the North Passenger Carshop and the South Passenger Carshop.

The Annex Building was built alongside the roundhouse on Poppleton Street to serve as a storage and service area.

The B&O built this car repair shed in 1919. Although it was nicknamed “tender kitchen” because it was occasionally used for repairing locomotive tenders, it was primarily used for repairing freight cars.

The National Road (also known as the Cumberland Pike or Cumberland Turnpike) was the first American highway funded by Congress.

The Underground Railroad was an American network of abolitionists who aided and sheltered enslaved people seeking freedom prior to the end of the Civil War and Emancipation in 1863.

On February 17, 2003, the roof of the 1884 Baldwin Roundhouse on the B&O Railroad Museum’s campus collapsed due to record snowfall in Baltimore of more than 28 inches.
