· 2006: rail to Tyson?s and Blue Line reconfiguration to divert one-half of the Blue Line trains across the Yellow Line bridge through L?Enfant Plaza rather than Rosslyn, to accommodate additional Orange Line trains from Tyson?s (and from Dulles/Loudoun County by 2010).
What? And just where will these trains go? Franconia-Springfield to Greenbelt? Mt Vernon Sq? Will the Yellow Line even exist anymore?
Then again, they could do it like this: Run trains from Largo to National Airport and from Greenbelt/Mt Vernon Sq. to Franconia-Springfield The idea is to make room for the trains from Tyson's Corner/Dulles Int'l Airport/Loudon County. Does that mean to choke out the Yellow Line instead? Because I don't see any way for them to run from Larog to Franconia-Springfield using the Potomac River Bridge, and having half the Blue trains in the Yellow/Green segment... one of the three lines is gonna get strangled by the other two.
On the other hand, they could build a flying junction that either bypasses L'Enfant Plaza, or goes through it, and then ducks out of the Blue/Orange tracks, and picks up the Yellow Line tracks. But, if they go through all that, they might as well just tunnel under the river, and connect at Pentagon or National Airport (they could do that, right? Or would they be forced to connect between National Airport and Braddock Road (probably near the Potomac Yard area))
