"Do you like the front or the back of the train?"

"The back by choice."

"First-class, isn't it?"

"Yes, first-class."

The porter, who had stopped a moment, picked up the heavy valise again.

"Then there isn't any choice. There are only two first-class carriages on the slow train, and they are both in the middle."

"They are corridor carriages, I suppose?" said Etienne Rambert.

"Yes, sir; there are hardly any others on the main-line trains, especially first-class."

In the ever-increasing crowd Etienne Rambert had some difficulty in following the porter. The Gare d'Orsay has little or none of the attractiveness of the other stations, which cannot fail to have a certain fascination for any imaginative person, who thinks of the mystery attaching to all those iron rails reaching out into the distance of countries unknown to him. It is less noisy than the others also, for between Austerlitz and Orsay the traction is entirely electric. And further, there is no clearly defined separation between the main and the suburban lines.

On the right of the platform was the train which was to take Etienne Rambert beyond Brives to Verrières, the slow train to Luchon; and on the left of the same platform was another train for Juvisy and all the small stations in the suburbs of Paris.
