This map shows what the transportation system of the Baltimore-
Washington area would look like if most of the proposed improvements are built. In particular, it includes the Silver Line to Dulles; several new infill Metro stations; turning MARC and VRE into transit-like service with frequent trains that run through from Maryland to Virginia so all commuters can reach Union Station, L’Enfant Plaza, Crystal City, and Alexandria; and light rail lines in the District, Northern Virginia, and Maryland including the Baltimore expansions that have been proposed.
Thanks for the many comments left on version 1 of the Greater Washington Transit Future fantasy map. I’ve added in almost all of the lines suggested in those comments (Columbia Pike streetcar, Potomac Yards transitway, light rail to Waldorf, etc.) I’ve incorporated the Baltimore expansion proposal (map and report), everything suggested by MWCOG (see page 3), rail expansion on those lines that still exist (some have been reused for Baltimore Metro or as rail trails), and the MARC growth plan (trying my best to figure out where the stations would be—that document is pretty vague).

Update 4/23/08: I had made a couple of small tweaks as a start on a version 3 of this map, but never finished it; I’ve now updated this map to include those changes. Most notable is an extra branch of the Corridor Cities Transitway, the more direct route ACT is pushing for, and a light rail up Columbia Pike from Silver Spring to Columbia Town Center along the route suggested by Dan of Just Up the Pike. The older version is here.
