Further explanation forthcoming, but at the GGW meet-up in Silver Spring tonight, a couple folks asked me about it, so here it is
What is on it?
-Potential extension of existing and under construction Metro Lines (including Silver), separated from each other to maximize capacity
-Two Metro Light Rail lines, the Purple Line (proposed) and the Black or "Columbia" Line (which hits Columbia Pike in MoCo, Columbia Heights, and Columbia Pike in VA)
-A vision for DC streetcars (red), Ride-On streetcars (light blue), streetcars for municipalities in Prince George's (various blues and purples), ART/DART (light green) and Fairfax Connector (white)
-Southern Maryland Area Rail Transport (SMART light rail, in yellow)
What's not on here yet:
-Corridor Cities Transitway
-A "Pink Line" heavy rail inner loop
-A "Brown Line" crosstown light rail
I probably won't add these, it doesn't mean I don't think we should have them:
-Rapid/express bus (vision supplants most of this with rail anyway)
-Redevelopment and suburban ruralization that would ideally accompany this sort of plan
-Bicycle facilities (not my wheelhouse... yet)
-New/changed/removed freeways, parkways, and interchanges, as well as newly tolled roads
Here's a disclaimer: I am not under the delusion that this vision is feasible, politically expedient, affordable, cost effective, or in any other way possible. But I imagine it would be able to quickly and safely transport most of the area's growing population after gas prices breach the threshold of affordability.
Sorry I am currently incapable of putting together a beautiful graphic like many of my fellow transit nerds at BeyondDC, Track Twenty-Nine, or Greater Greater Washington, but hopefully the arrangement I have thrown together on GoogleMaps will give people an idea of what I'm going for here.
