Based on an exert from Huysman's A Rebours: 'One of these, bearing the name of Crampton, is an adorable blonde with a shrill voice, a long slender body imprisoned in a shiny brass corset, and supple catlike movements; a smart golden blonde whose extraordinary grace can be quite terrifying when she stiffens her muscles of steel, send sweat pouring down her steaming flanks, sets her elegant wheels spinning in their wide circles and hurtles away, full of life, at the head of an express or boat train. The other, Engerth by name, is a strapping saturnine brunette given to uttering raucous, guttural cries, with a thick-set figure encased in armour-plating of cast iron; a monstrous creature with her dishevelled mane of black smoke and her six wheels coupled together low down, she gives an indication of her fantastic strength when, with an effort that shakes the very earth, she slowly and deliberately drags along her heavy train of goods-wagon.
