He went up the stairs, then past the semi-circular hatch (through which the platform from which he’d just risen was visible), with its onrush of air each time a train approached or after it departed—invisible gust, by which you knew a journey’s aftermath or closeness. His uncle and he had strolled past the hatch a hundred times in their lackadaisical way: they never hurried for the trains, not even upon being warned by that warm breeze. Through the collapsible doors on to the spherical cage, the lift. More than anything—escalator or staircase—this antique piece of ironwork was his connection to what was subterranean here.
