Northern Central Railroad Baltimore Freight Shed
Built by the Northern Central Railroad, the former Baltimore Freight Shed is a rare example of composite timber and iron roof construction of the mid nineteenth century.
The roof structure is comprised of a series of tricomposite trusses with timber top chords, wrought iron tension rods, and cast iron compression members. This use of both timber and iron in the same roofing system formed a transition period between short span timber trusses and longer span iron and steel trusses that would be in widespread use by the end of the century. The building remains in use today as the home of the Merritt Downtown Athletic Club.
