If you’re a New Yorker with a Windows Phone then there’s a new (free) app for you called MTA Information for you:
MTA Information is a must-have for every New Yorker who uses the MTA to get where they need to go. The app will give you the most updated status of all MTA transportation methods. The methods include the Subway, Buses, Bridges and Tunnels, LIRR and MetroNorth. The app also gives you quick access to the Maps for the Subway, LIRR, Metro-North, Bridges and Tunnels and the Staten Island Railway. The best features is the ability to find all the subways near your current location (you will need location services enabled). When you find the subway you want to reach, you can click the subway and directions will be given.
