In January 1847, an investigation was opened into projects towards Geneva, Besançon, Dôle-Châlons. In 1850, the Lyon Chamber of Commerce and Industry adopted the project for a rail link from Lyon to Chambéry via Saint Genis sur Guiers. Applications to operate this line were rejected until 1877. The work lasted 4 years, financed in part by Belgian capital. The inauguration took place on October 9, 1881, and the first train ran on October 30. The line started from the Gare de l'Est (Avenue Félix Faure) and ended at Sablonnières. It had 16 stations and 3 stops over a distance of 72 Kms. Passenger traffic increased from 4 daily round trips in 1897 to 8 in 1935. A passenger took 40 minutes on the 6:35 AM train to travel from Lyon to Pont de Chéruy and 34 minutes to return to Lyon on the 7:23 PM train. Despite everything, the line was closed to passengers in December 1938, then reopened from September 1939 to December 31, 1947. VFD (Voie Ferrée du Dauphiné) coaches took over between Crémieu and Lyon; Freight traffic supplied the main industries (Grammont in Pont de Chéruy and Vicat in Bouvesse) as well as the various industrial zones. The network served 70 private sidings. At its peak in 1935, 1,000,000 tons transited through this line. The decision by the cement factories to no longer use the rail in 1978 was to deal it a "fatal" blow. In 1980, during its last year, 540,244 tons (including 150,130 of scrap metal) were still transported. In 2001, CoUrLy (Urban Community of Lyon) and the General Council of the Rhône adopted a decision to reactivate passenger traffic on part of the route of the Est line. The objective is to connect Lyon to Saint Exupéry airport.

The Chemin de fer de l'Est de Lyon (CFEL) is a former French secondary railway network with standard gauge located partly in the Rhône department and partly in the Isère department and which connected the Gare de Lyon-Est to Aoste-Saint-Genix via Crémieu, Saint-Hilaire de Brens (Turnoff for the Jallieu antenna) and Soleymieu-Sablonnière (Turnoff for the Montalieu antenna). After a gradual end of operation until December 2003, the area of the line between Lyon-Part-Dieu station and Meyzieu Z.I. was transformed to allow line T3 of the Lyon tramway to run there, and the Rhônexpress shuttle to Saint-Exupéry airport. Note for the latter, that from the Meyzieu ZI, the track leaves the former CFEL right-of-way to head south towards the airport.
