Baltimore and Ohio Railroad Museum

Pratt Street runs west to the Mount Clare Railroad Station of the Baltimore and Ohio Railroad, from which the first passenger train in the United States ran west to Ellicott's Mills in 1830.

The Baltimore and Ohio Railroad Museum takes in the Mount Clare Station (1851), the Print Shop (1884) and a roundhouse that now houses an excellent collection of historic locomotives. The centrepiece is the turntable, which connects with 22 lines containing locomotives and coaches. With only a few exceptions all the exhibits are originals and in working order. In front of the building is a large open area with more locomotives. There is also a miniature railway system.
