Boston's MBTA has had similar services available for years. About 3 years ago they rolled out tracking for the Orange, Red and Blue lines. Less than 2 years ago, they rolled out GPS tracking for buses. Recently, they started adding arrival time boards for the Orange, Red and Blue Lines as well. * MBTA App Showcase: http://www.mbta.com/rider_tools/apps/ http://www.mbta.com/rider_tools/apps/ * MassDOT Developer Page: http://www.eot.state.ma.us/default.asp?pgid=content/developer&sid=about http://www.eot.state.ma.us/default.asp?pgid=content/develope... Additionally, cellular service has been added to most subway lines and stations for at least the orange line (so you have decent signal while riding and in stations), plus WiFi available on most commuter rail trains.
