Exposition internationale des industries et du travail de Turin 1911 (Paris: Comite Francais des Expositions a l'Etranger, 1911), p. 18. Works numbers 7703-7704 in 1910 and 7884 in 1911.
This little railway was opened in1868 once it reached Venaria Reale. By 1869, the line had five stations along 21.24 km (13.2 mi) running northwest from Turin to end at Cirie and later reached Lanzo, some 32 km (19.9 mi) from Turin. Its role was to haul secondary mixed traffic on a relatilvely light railway.
In 1916, the line opened an extension 10 km (6.2 mi) further to Ceres. This last stop left the railway just 25 km (16 miles) from the French border.
