The Terni–Sulmona railway is a regional railway line in central Italy, managed by Rete Ferroviaria Italiana. It links three regions, Umbria, Lazio and Abruzzo, and three provincial capitals: Terni, Rieti and L'Aquila. Together with the Sansepolcro-Terni and the Sulmona–Isernia railways, it forms a 440Km-long North–South corridor through the Apennines in central Italy. In December 2021, Italy's Ministry of Transport included the Terni-Sulmona among the first local railways to be converted from diesel to hydrogen.
Its route is the result of two unfinished railways that had to meet in Rieti: the Pescara–L'Aquila–Rome line, and the Terni–Avezzano–Roccasecca line.
