Easily Impressed

This subway map was on a line 2 train. The stop that the train is at lights up, and the arrows also light up to indicate which direction the train is headed. Way cool. Of course, after I saw this one (and I totally thought it was a special line 2 thing),  I saw another one like it on a line 7 train. Instead of arrows it had little dots in between stops that lit up as you got closer to the station.
