Known as the Sulcis Railway, this narrow-gauge line was built in the 1920s by the Ferrovie Meridionali Sarde (Sardinian Southern Railways) to connect the mining areas of Sulcis with coastal towns and ports of embarkation. The route passed through isolated landscapes and wooded valleys, serving villages and mines that are now partly abandoned. Today, bridges, tunnels, and disused stations remain, testifying to the era when the railway was the main means of communication for miners and goods in the southwest of the island.
