It’s been available as a layer on Google Maps for BlackBerry devices for a while, but it looks like Google formally announced the MTA NYC Subway transit layer for the standard version of Google Maps. Rather than simply showing the station stops like Google Maps has been doing, the new layer actually shows you how each line travels from point to point.
Looks like there will soon be no use for this digital version of the official MTA NYC Subway map.
i finally figured out how to use the subway today!
