Streetcar conduit track
The last streetcar ran in the capital in 1962, on this street in 1960, but the track is still in place on two streets. The centre line is the conduit for electric power. This is P street - which with O street formed a terminal loop.
Wikipedia has a useful map and lots more information. Conduit current colection was mandated by congress in the capital - as also happened in central London and a few other cities.
