Here's something I've been working on for quite a while now. A fantasy Philadelphia metro transit network, projected full buildout ca. 2050. While I don't expect everything to come to fruition in my lifetime, some things in here are eminently achievable in the short term if planners and pols actually gave a fuck about improving SEPTA.
