Expanding the Metro....

David, in "WMATA fantasy combo map" in the Greater Greater Washington blog, is taking a crack at conceptual maps for transit expansion including the Purple Line, an extended green line (we won't talk about that), and the separated blue line and new brown line idea for enhanced heavy rail transit within DC.

I will use a revised version of this map in my forthcoming revision to the 2008 Transit/Transportation wish list later this week.
