Piraeus–Platy railway line

Piraeus–Platy railway line. The Piraeus–Platy railway line is the principal north-south railway corridor in Greece, connecting the major port of Piraeus with the central railway junction at Platy near Thessaloniki. Spanning approximately 510 kilometers, it serves as the backbone of the national rail network, linking the Attica region with Central Greece, Thessaly, and Central Macedonia. Operated by Hellenic Train and owned by the state asset management company GAIAOSE, the line is vital for both long-distance passenger services and freight transport between the country's primary urban and industrial centers.

Route and stations

The line originates at Piraeus railway station, a major hub integrated with the Athens Metro and Proastiakos suburban services, and proceeds north through the Athens metropolitan area. Key stations in Attica include the central interchange at Larissa Station in Athens, Acharnes Railway Center, and Inoi. It traverses the scenic landscapes of Boeotia, passing through Livadeia and Lianokladi, before entering the Thessaly plain and serving the critical junctions of Larissa and Paleofarsalos. North of Larissa, the route ascends through the Tempe Valley near Mount Olympus, continues past Katerini, and terminates at the strategic Platy station, which provides connections to lines towards Thessaloniki, Florina, and Alexandroupoli.

History

The construction of the line was a monumental project undertaken in several stages during the late 19th and early 20th centuries, reflecting the expansion of the Kingdom of Greece. The first segment from Piraeus to Athens opened in 1869 by the Piraeus, Athens and Peloponnese Railways, with the section to Lianokladi completed by 1904. The challenging connection through the Tempe Valley was finished by 1916, finally creating a continuous link to the Thessaloniki network following the territorial gains after the Balkan Wars. The line played a crucial logistical role during the Macedonian front of World War I and the subsequent Greco-Turkish War (1919–1922). Major modernization, including double-tracking and electrification, was carried out in the late 20th and early 21st centuries, significantly funded by the European Union.

Technical characteristics

The railway is built to standard gauge and features extensive double-track sections, particularly on the southern part from Piraeus to Inoi and north of Larissa. It is electrified at 25 kV AC OHLE from Piraeus to Thessaloniki, allowing the operation of modern electric multiple units like the ETR 470 and Stadler FLIRT. The line includes significant engineering works such as the Tempe Valley passage, numerous tunnels through the Othrys and Olympus mountain ranges, and major bridges over rivers like the Spercheios and Pinios. Maximum permitted speeds reach 160 km/h on upgraded segments, though mountainous terrain imposes lower limits in certain sections.

Services and operations

The line hosts a dense mix of intercity, regional, and suburban passenger services operated by Hellenic Train. Premier long-distance services, including the overnight trains to Thessaloniki and northern Greece, utilize this corridor. The Proastiakos suburban network serves the Athens urban area from Piraeus to Chalkida. It is also a critical artery for freight transport, connecting the container terminal at Piraeus Port, managed by COSCO Shipping, with intermodal logistics centers in Thriasio and Larissa, and onward to markets in the Balkans and Central Europe. Operations are coordinated from the Athens and Thessaloniki signaling centers.

Future developments

Future projects aim to fully integrate the line into the broader European high-speed rail network. The central piece is the new high-speed line between Athens and Thessaloniki, which will run parallel to sections of the existing corridor, drastically reducing travel times. Upgrades are also planned to improve capacity and speed on the conventional line, particularly for freight. These projects are part of the Trans-European Transport Network (TEN-T) and are largely financed by the European Union through the Connecting Europe Facility. Further integration with other transport modes is envisioned at key hubs like Larissa and the new Athens International Airport station.
