Roubaud was interested for a few minutes, comparing what he saw with his own station at Havre. Each time he came like this, to pass a day at Paris, and found accommodation in the room of Mother Victoire, love of his trade got the better of him. The arrival of the train from Mantes had animated the platforms under the marquee of the main lines; and his eyes followed the shunting engine, a small tender-engine with three low wheels coupled together, which began briskly bustling to and fro, branching off the train, dragging away the carriages to drive them on to the shunting lines. Another engine, a powerful one this, an express engine, with two great devouring wheels, stood still alone, sending from its chimney a quantity of black smoke, which ascended straight, and very slowly, through the calm air. But all the attention of Roubaud was centred on the 3.25 train for Caen, already full of passengers and awaiting its locomotive, which he could not see, for it had stopped on the other side of the Pont de l'Europe. He could only hear it asking for permission to advance, with slight, hurried whistles, like a person becoming impatient. An order resounded. The locomotive responded by one short whistle to indicate that it had understood. Then, before moving, came a brief silence. The exhaust pipes were opened, and the steam went hissing on a level with the ground in a deafening jet. He then noticed this white cloud bursting from the bridge in volume, whirling about like snowy fleece flying through the ironwork. A whole corner of the expanse became whitened, while the smoke from the other engine expanded its black veil. From behind the bridge could be heard the prolonged, muffled sounds of the horn, mingled with the shouting of orders and the shocks of turning-tables. All at once the air was rent, and he distinguished in the background a train from Versailles, and a train from Auteuil, one up and one down, crossing each other. As Roubaud was about to quit the window, a voice calling him by name made him lean out. Below, on the fourth floor balcony, he recognised a young man about thirty years of age, named Henri Dauvergne, a headguard, who resided there with his father, deputy station-master for the main lines, and his two sisters, Claire and Sophie, a couple of charming blondes, one eighteen and the other twenty, who looked after the housekeeping with the 6,000 frcs. of the two men, amidst a constant stream of gaiety. The elder one would be heard laughing, while the younger sang, and a cage full of exotic birds rivalled one another in roulades. "By Jove, Monsieur Roubaud! so you are in Paris, then? Ah! yes, about your affair with the sub-prefect!" The assistant station-master, leaning on the rail again, explained that he had to leave Havre that morning by the 6.40 express. He had been summoned to Paris by the traffic-manager, who had been giving him a serious lecture. He considered himself lucky in not having lost his post.
