Steamtown National Historic Site (NHS) is a railroad museum and heritage railroad located on 62.48 acres (25.3 ha) in downtown Scranton, Pennsylvania at the site of the former Scranton yards of the Delaware, Lackawanna and Western Railroad (DL&W). The museum is built around a working turntable and a roundhouse that are largely replications of the original DL&W facilities. The site also features several original outbuildings dated between 1899 and 1902. The roundhouse was reconstructed from remnants of the 1932 facility. All the buildings on the site are listed with the Natiopnal Register of Historic Places as part of the Delware Lackawanna and Western Railroad Yard-Dickson Manufacturing Co. State.
Most of the steam locomotives and other railroad equipment at Steamtown NHS were originally collected by F. Nelson Blount, a millionaire seafood processor from New England. In 1964, Blount established a non-profit organization, the Steamtown Foundation, to operate Steamtown, USA, a steam railroad museum and excursion business in Bellow Falls, Vermont. In 1984, the foundation moved Steamtown to Scranton, conceived of as urban redevelopment and funded in part by the city. But the museum failed to attract the expected 200,000 to 400,000 annual visitors, and within two years was facing bankruptcy.
