So, ok, we know that the DC Metro is beset by almost innumerable issues. Equipment and trains break down. Trains run behind schedule, and are overcrowded. Things are so bad that after years of record ridership, people aren't using the system anymore.
This started as a thought exercise. What if we could change the way people thought about the metro? Like the system or not, you can't argue it is successful as a rapid transit system. It's inefficient as a way to get around the city. But it excels at getting people in and out of the city. What if we thought of the system as a commuter rail system on par with MARC or VRE? Would that encourage people living and commuting within the district to ease the burden on the system and use buses? Would it give the system the public support to build light rail or a (good and robust) streetcar system? A map can't do it by itself, but this would be a step there.
