A Subway-Style Map of San Francisco's Historical Trains
It was created using a collection of 1937 railway timetables.
David Edmondson explores his passion for transportation through his blog and his Twitter account. In response to his online musings about how Bay Area trains ran in the 1920s and 1930s, one of his readers sent him a 1,500-page national collection of 1937 railway service timetables. Using this document, Edmondson visualized the train service in and around San Francisco from the time—in the form of a subway-style map (click through to enlarge the image).
