Recently, I stumbled upon a news video on YouTube saying that the MTA is working on bringing Cellular Service & WiFi to the subway system, starting with the S line (The 42nd Street Shuttle). I'd say this is a nice thing for them to do, despite it being expensive, and though I semi-rarely ride the New York City Subway, it will be nice for the times I do, and for all the other commuters who will have a nice connection to the internet, especially if most of their trip is underground. In the news article, it seams that commuters are very happy about this change. MTA officials claim that the next focus is the (G) line, which is nice for them, considering they recently finished the project that got them CBTC. This isn't too big of a deal, at least since it's only a 90-second ride, but, as it gets to bigger lines, it will become very handy.
