How not to design a diagram. This thing fails miserably at answering the one question it’s designed to answer: “Where can I fly on Frontier Airlines?” It gives you lots of information that doesn’t matter (geography) and displays the important information (what routes they fly) poorly. Just try figuring out whether you can fly from Denver to Columbus non-stop. I dare you.
Los Angeles 2020. Since my last map of Los Angeles was posted, LA Mayor Villaraigosa and the Los Angeles MTA have decided to accelerate their subway construction timetable. A lot. For comparison, this is what the system looks like now. By 2020, LA should have the second-largest subway system in the U.S., after New York.
Bay Area 2009. With the BART system cut down to half-size, the Southern Pacific commuter trains survived into the modern day as the CalTrain commuter service. Soon, CalTrain will be upgraded into a four-track rapid transit line, and Marin is getting its own commuter service, SMART. 50 years late, but better late than never.
BART 1961 Plan. One of the little-known things about the original BART system is that it was only half-built. In the early 1960s, San Mateo and Marin both pulled out of the BART district: Marin because the Golden Gate Bridge directors didn’t think the Bridge would carry a pair of tracks, and San Mateo because local merchants were afraid of losing shoppers to San Francisco.
