The railway from Piraeus to Patras was a 230-kilometre-long (140 mi) metre-gauge railway line in Greece that connected the port of Athens, Piraeus with Patras in the Peloponnese peninsula, via Athens "Peloponnese" central station and Corinth. It was opened between 1884 and 1887. Formerly one of the main lines of the Greek railway network, it has now largely fallen into disuse. It has mostly been replaced by the Athens Airport–Patras railway, a new standard-gauge line whose first section opened in 2004 and which remains under construction between Aigio and Patras. The 13 km (8.1 mi) section between Piraeus and Agioi Anargyroi, a northern suburb of Athens, has since been removed and replaced by the corresponding section of the upgraded Piraeus–Platy railway. As of 2020, the only sections in operation are the 22.5 km (14.0 mi) section between Agioi Anargyroi and Eleusis, and the 7.3 km (4.5 mi) section between Rio and Patras.
