This is the first edition from 1915, published by the "General Directorate" and "Traction Service" of the Italian State Railways, of two large volumes of "Locomotive and Automotrici" nomenclature, issued to the 6th Railway Regiment of the Royal Army.
The 6th Railway Regiment was provided with these two nomenclatures for instruction or to learn the nomenclature and characteristics of the locomotives and autometrics in use at the time.
Each volume contains numerous plates, cross-sections, and technical data.
