The Pont de Demay stop is part of the Voiron–Saint-Béron line—a branch line that operated from 1895 to 1936 along a 35-kilometer route between Isère and Savoie.

The line carries passengers and freight, particularly metal products from Saint-Laurent-du-Pont and Fourvoirie, as well as those from the Chartreuse distillery.

In the photograph, about ten men are posing in front of the wooden shelter at the train stop—some are wearing business suits, bowler hats, and felt hats; a few are in work clothes. In the background, dump trucks and a construction crate suggest that the photograph was taken during construction or shortly after the line opened, around 1895.
