The list of secondary, industrial and Decauville railways in Argentina includes narrow-gauge railway lines that operated in Argentina, which used tracks, sleepers, or vehicles manufactured by French company Decauville.
[1][2] The vast majority of those lines were freight services, although in some cases (such as the Ostende railway or the Yerba Buena Steam Tram) also ran passenger services.
