This little railway was opened in 1868 once it reached Venaria Reale. By 1869, the line had five stations along 21.24 km (13.2 mi) that ended at Cirie and later reached Lanzo, some 32 km (19.9 mi) from Turin. And in 1916, the line had extended 10 km (6.2 mi) further to Ceres.

This close-coupled Mogul tank had a Belpaire firebox with a sandbox and steam dome and immediately ahead and grouped closely together.
