Washingtonian (B&O train)
The Washingtonian was one of two daily American named passenger trains operated by the Baltimore and Ohio Railroad (B&O) during the 1940s–1950s between Baltimore, Maryland and Cleveland, Ohio, via Washington, D.C., and Pittsburgh, Pennsylvania. It was the last B&O long-haul passenger train to be powered by a steam locomotive from the venerable railroad's namesake city.
