The Florida East Coast Railway's tracks (along with the land around them) are probably one of South Florida's most underutilized assets. The rail line goes through pretty much everywhere - urban cores, highly-trafficked roads, residential, commercial, industrial, airports, seaports, everything. All Aboard Florida and an expansion to Tri-Rail are both coming to the FEC line, but what if urban planners went all out, adding things like a trolley line, bike trail, promenade, frequent stations, farmers markets, lush landscaping, parks, transit-oriented developments around each station, etc. ect. etc.? You'd get something like what the creator of this Facebook Page FEC Rail Development Opportunities For The People, a guy named Jack, is proposing = a crazy intense, and admittedly fascinating, linear spine of transit and urbanity. Some of his many drawings are above, with many more here.
