I noticed this big box that looks like it fell off of a ship on the north side of P St NW near the corner of 16th. A quick Google search for T.U.S.&S. (the letters on it) show that the company makes switch and signal equipment for railroads, but there’s no trains anywhere near here! What is this thing? Could it be leftover from an old trolley line? Were there ever trolley’s on P Street?
