Piraeus, Athens and Peloponnese Railways or SPAP (Greek: Σιδηρόδρομοι Πειραιώς-Αθηνών-Πελοποννήσου "Siderodromi Pireos Athinon Peloponisou" or Σ.Π.Α.Π. (S.P.A.P.); French: Chemin de fer du Pirée-Athènes-Peloponèse) was a Greek railway company founded in 1882, which owned and operated the 1,000 mm (3 ft 3+3⁄8 in) (metre gauge) Piraeus–Patras railway line connecting Piraeus and Athens to Peloponnese. The company was nationalized in 1954 and absorbed by the Hellenic State Railways in 1962. The name "Spap" originates from the Greek initials of the railway company.
