Plans are afoot for even more pneumatic tubes in New York City, already home to the Roosevelt Island tubes and the Hudson Yards developments, as well as many others in the world of fiction and cinema. This time it is the High Line which might be tubed for waste disposal, quoted in The Atlantic's CityLab as perfect for such infrastructure considering that "the tube could be strung along the bottom of the viaduct, avoiding any need to tunnel through streets".
