A locomotive testing facility in the midst of a residential area, where boys sneak through the fence to watch them test how much mass a big engine can pull? Why, that's a Tractive Nuisance!
Meanwhile, a chemical plant's open, ceramic-tiled pool of sulphuric acid, complete with ladder and diving board? That's a Subtractive Nuisance. No diving!
(Neither term, thank goodness, prompted by a news item).
