      This Yellow Line train is at its Huntington terminal in 
		Fairfax County.  The route's other terminal is the only one on any 
		line that is in the District of Columbia itself, at Fort Totten, where 
		the Red Line crosses underneath.  The final nine stations north on 
		the Yellow are shared with the Green. 
		 
		Metro crosses the Potomac River along two different 
		routes.  The Blue and Orange Lines share a tunnel between the 
		Rosslyn and Foggy Bottom-GWU stations.  The Yellow Line takes a more 
		direct route from the south over a much more direct bridge located not 
		far from Amtrak's crossing of that historic waterway.   |
