Google Launches Subway Alert App

Launched yesterday by Google Maps:

Have you ever arrived at a subway platform only to find that the train you intended to take is skipping stops, rerouted on another line, or isn't running at all due to scheduled maintenance? Now when you click on any of the 468 New York City subway stations labeled on Google Maps, you’ll see whether any planned service changes are expected to affect that station at the time. In addition, the relevant alerts will be included in the step-by-step transit directions pointing you wherever you’re going.
