Thessaly Railways was a private railway company in Greece, which owned and operated the metre gauge railway network of Thessaly and Pelion railway from 1884 to 1955, when the private company was absorbed by the Hellenic State Railways state-owned company. Today the term usually refers to the section of mainline between Domokos and Rapsani and its two branches, the West Thessaly branch to Kalambaka and the Volos branch.
