Anyone curious and not in the know:

This is the station information screen in a Washington D.C. Metro (subway) station.

First column is Line, blue, blue, orange.

Car is how long the train is. (This one is pretty obvious)

Destinations are Foggy Bottom, Largo, and New Carrollton.

Last column is how many minutes until the train arrives and the floor lights start blinking.

The DC Metro is great, and it hardly ever catches on fire.
