MTA New York City Transit (NYCT) has installed countdown clocks at all stations on the E and G rail lines to provide real-time arrival information.
The agency is using so-called "beacon technology" to power the clocks. The technology involves putting four low-energy Bluetooth beacons on each trainset and two receivers on each platform. LCD display screens at the stations then use that technology to provide real-time arrival information, NYCT officials said in a press release.
