Can someone identify the time period for this? This is Cedar St. looking east at the intersection with 4th St., where the railroad (now the Metro) crosses over it.
View looking from the northwest corner of Cedar and 4th Street NW east down Cedar Street toward the railroad underpass. Image includes a partial view of the Baltimore & Ohio Railroad station on the right with a blurred locomotive crossing the underpass and going into the station. The train is headed toward Washington, D.C.
