IanVisits has stumbled across Transport for London’s cache of car line diagrams (CLDs)—the linear maps that appear inside each train car. The TfL page includes CLDs ands CLD stickers for all lines going back to 1996; each line has its own PDF file that contains every iteration of its diagram, one per page. “No one will care about this whatsoever,” says IanVisits. IanVisits is, I suspect, wrong. [WMS]
