Via the always engrossing Things Magazine, we are treated to a very nicely curated interactive gallery of the charts and strip maps of artist Jake Berman (previously) that allows one to compare historic public transportation systems (see also) with their modern equivalents for several US cities.
Reaching back more than a century in some cases, Berman plots old train and street car routes—or ambitious proposals pared back versus their contemporary circuits and study in detail how coverage has expanded or contracted.
