Mount Clare Shops
Coordinates: 39°17′08″N 76°38′00″W / 39.285457°N 76.633437°W The Mount Clare Shops is the oldest railroad manufacturing complex in the United States, located in Baltimore, Maryland. It was founded by the Baltimore and Ohio Railroad (B&O) in 1829. Mt. Clare was the site of many inventions and innovations in railroad technology. It is now the site of the B&O Railroad Museum. The museum and Mt. Clare station were designated a National Historic Landmark in 1961.
The Mount Clare site was a portion of an estate owned by Charles Carroll (barrister), a distant cousin of Charles Carroll of Carrollton. (See Mount Clare (Maryland).) The initial operations of the B&O used horsecars, and the earliest facilities on the Mt. Clare site included a depot and stables for horses. This was one of the earliest passenger stations in the United States.
Following the 1830 manufacture of the first U.S. steam locomotive by Peter Cooper at the nearby Canton Iron Works, the B&O began building locomotives at Mt. Clare, as well as freight cars, passenger cars, bridges and other railroad equipment. Ross Winans and Phineas Davis, pioneers in locomotive design, built their inventions at Mt. Clare. The shops employed 100 workers in 1839.
