New MTA App Tells Commuters When Their Train Will Arrive

NEW YORK — A new app aims to make fewer straphangers feel stranded by train delays.

MTA Subway Time — which launched as a beta version for iPhones, iPads and the iPod touch on Friday — gives riders on seven subway lines real-time information about train arrivals, according to agency officials. A desktop version is available on the MTA website.
