Combating an “olfactory nuisance”: Apparently London Underground is going to start perfuming Tube stations. The idea originated in France, where the Metro has been “perfuming platforms for three years with Madeleine, a scent named after one of its smelliest stations.” Starting Monday, Euston, St James’s Park and Piccadilly Circus will hopefully smell of a “fresh watery floral bouquet of rose and jasmine combined with citrus top notes, giving way to strong woody accents and a hint of sweetness in the base” as opposed to the “earthy concoction of sweat, fast food and mouse droppings that is the real l’air du Tube.” I’ll give you a review as soon as I can.
