Awesome discover, Pablo! The geographical map is reasonably clumsy and unremarkable, but the diagram beneath is incredibly interesting. It is what I contact a “linear diagram” – each and every route is shown as a straight line, with interchanges indicated by a vertical signing up for line or bar. It is not entirely unique (see this more latest illustration from St. Petersburg), but it’s not a variety that’s at any time been incredibly well-known. It only truly will work for comparatively uncomplicated networks with a several obviously outlined interchanges… Madrid’s 4 short traces at the time built it a best candidate for these a diagram.
