In 1871, following the end of the Franco-Prussian War, France lost Alsace-Lorraine to Germany. This drastically reduced the territory served by the CF de l'Est. As a result, the "Gare de l'Est" was developed to become the CF de l'Est's main station in Paris. Although the "Gare de la Bastille" was only a local terminus, by 1889 it was the second busiest in Paris, handling 12,000,000 passengers per annum. The "Ligne de Vincennes" was extended to Verneuil-l'Étang in 1892, making it long. The station served commuters during the week, and Parisians escaping to the country on weekends. By the 1920s, the "Gare de la Bastille" was handling 30,000,000 passengers each year. Electric traversers were installed to allow longer trains to be handled.
