Police Call Boxes such as this one (originally painted blue) were installed in the District after the Civil War. Officers on foot patrol used this secure telegraph system to contact the station, accessing the box with a now highly collectible "gold key." This system was used until the late 1970s when it was abandoned in favor of more modern communication methods.
