Located on the northern Peloponnese, it runs 22 km from Diakofto through the Vouraikos Gorge and the Mega Spilaion monastery and up to Kalavryta, stopping en route at Zachlorou. The line was built by the Piraeus, Athens and Peloponnese Railways (SPAP). Currently the infrastructure and rolling stock are owned and maintained by the Hellenic Railways Organisation (OSE).
