Today I am suggesting the Washington Metro Blue, Orange and Silver Lines from Rosslyn to Stadium-Armory. The characteristics that make this route unique is that it is underground and features crossing underneath the Potomac River between Rosslyn and Foggy Bottom-GWU stations, underneath James Monroe Park between Foggy Bottom-GWU and Farragut West stations, underneath Farragut Square and McPherson Square between Farragut West and McPherson Square stations, underneath Franklin Square, McPherson Square and Metro Center stations, underneath the Victory Garden and the National Mall between Federal Triangle and Smithsonian stations, underneath 12th Street SW, the 12th Street Expressway and CSX RF& R Subdivision between Smithsonian and L’Enfant Plaza stations, underneath D Street Rolling Stock: Kawasaki 7000 Series
