New York City set to launch subway-tracking app for seven of the city’s 24 lines

Skift Update: Subway Time is now available for free in the iTunes store.

America’s largest subway system is preparing to launch a smartphone application that will reveal train-arrival times on seven of the city’s 24 lines—a leap forward for a service that has lagged behind its peers both at home and abroad in adopting new technologies.

The Metropolitan Transportation Authority expects to release on Friday its Subway Time app for passengers with iPhones and iPod Touch devices. Android and Windows versions of the app are in development and the agency is currently considering how to integrate the real-time arrival information on its existing website.
