Diakopto–Kalavryta railway

The Diakopto–Kalavryta railway (Greek: Οδοντωτός σιδηρόδρομος Διακοπτού - Καλαβρύτων, romanized: Odontotós sidiródromos Diakoptoú - Kalavrýton) is a historic 750 mm (2 ft 5+1⁄2-in) gauge rack railway in Greece. Located on the northern Peloponnese, it runs 22 kilometres (14 mi) from Diakopto through the Vouraikos Gorge and the old Mega Spilaion Monastery and up to Kalavryta, stopping en route at Zachlorou. Today, the stations infrastructure and rolling stock are owned and maintained by the Gaiose and the line infrastructure Hellenic Railways Organisation (OSE) and passenger trains are operated by Hellenic Train. At the Diakopto terminus, the line connects with the new standard-gauge Athens Airport–Patras railway; as of 2019 the new track is in place in a cutting through the station yard.
