Trouble on the escalators at the Foggy Bottom Metro station is a common and reliable source of rider frustration. And, for as long as I can remember, people have been pining for somebody to take a stand and make the rules of escalator etiquette totally clear to others.

That said, behold!

Around ten of the signs were visible this morning inside the station, and the “rules and regulations” outlined therein are decent reminders, especially in a station which is so plagued by backups during the morning rush. We’re trying to figure out if this is merely a Foggy Bottom thing, or if there are other places where these have popped up — if you’ve seen them in any other stations this morning, let us know in the comments.
