The remnants of abandoned train lines are still visible to this day, often drawing curiosity from those David Edmonson calls "legacy train nerds." As a railway enthusiast himself, Edmonson wanted to know where these train lines once ran and decided to take it upon himself to map each line on a colorful, subway-style map. Utilizing 1930's railway timetables, he's completed a map of the San Francisco Bay Area's historical trains and is currently working on one for the Washington, D.C. and Baltimore areas. To create these and more maps, Edmonson started a Kickstarter project with a $250 goal that has already been exceeded and is currently heading towards $1,000. Edmonson spoke about his cartographic crusade with Curbed DC, explaining what inspired him to start this project and what other areas of the U.S. he hopes to cover.
