NYC Subway LED Signage / 20090923.SD850IS.3166 / SML
The signage is split into two halves. On the left side of the panel shows where the train is at while the train is stopped (with a flashing bounding box), and when it's in motion, it displays the next stop. The name of the next 10 stops, in yellow, are displayed to the right of 'you are here sign post'. Each station name is accompanied with designation in green which shows the additional lines you can do an interchange. A red handicapped icon designate whether there it is a station equipped with accessibility access.
At the end of the right half of the panel shows the last stop of the train, and the LED displays loops through the rest of the stop in multiple of 10s, so you can get a glance of all the stops while keeping the display small enough so as not requiring an extra large panel for the longer lines.
