Commenter Reza pointed out Track Twenty-Nine’s great visual diagram of the proposed Franconia-Greenbelt “blue line reroute”. He shows each train in a 12-minute period as a separate line, making it easy to visualize the relative volume on each segment of Metro track before and after the proposed change.

See the post for more details and an analysis of the relative time savings and costs (riders to L’Enfant should save an average of 9 minutes, while riders to Farragut West lose 6).
