The southern terminus of the Piraeus–Platy railway is at the harbour of Piraeus, where connections with ferries to several Greek islands exist. From Piraeus station, the line runs northeast towards the centre of Athens, where it crosses the main Athens railway station, commonly known as Larissa station. Continuing through the northern suburbs of Athens, the line runs to Agioi Anargyroi, where the old Peloponnese line branched off westwards. The metre-gauge track is still in place from this point on.
Platy, Imathia is the point where the nation's two largest cities were first linked by rail in 1916. Trains between the two commenced operations in 1918, with the first through train service from Athens to Paris linking up with the Orient Express, which was inaugurated in 1920. At Platy, the line from Piraeus connects with the line from Thessaloniki to Kozani (including the branch line to Amyntaio) and Florina.
Larissa and Thessaloniki have substantial marshalling yards for both goods and passenger trains. Journey time between Athens and Thessaloniki can vary depending on the type of train selected. Before the Tempi train crash, the regular InterCity service took 4 hours and 13 minutes, while the Express took 3 hours and 59 minutes. Following the implementation of lower operating speeds and other safety measures, the journey times have increased to 7 hours and 17 minutes and 5 hours and 18 minutes respectively.[6]
Stations
The main stations on the Piraeus–Platy railway are:
Although a railway line from Athens to the north had been planned since 1883, the first section from Athens to Demerli (current Palaiofarsalos railway station) was not opened until 1908. The two branch lines from Oinoi to Chalcis and from Lamia to Stylida were also opened in 1908. Subsequently, the line was extended towards the former Greek–Turkish border at Papapouli, between Larissa and Katerini. Finally, in May 1916, the remaining section from Papapouli to Platy on the line from Thessaloniki to Monastir (Bitola) was opened.[7]
Major upgrades to the line had been planned since the late 1980s. The first upgrade was completed west of Oinoi in the early 1990s. In 1996, the Orfana bypass was opened. On 28 November 2003, the Vale of Tempe line was abandoned in favour of a tunnel, and in 2004 the Tempe–Platamon–Katerini–Platy section was drastically shortened, leading to the abandonment of the picturesque route along the Aegean coast at Platamon. Between 2005 and 2010 several sections were upgraded in order to allow for higher speeds, notably the Oinoi–Tithorea, Domokos–Larissa, Evangelismos–Leptokarya and Aiginio–Thessaloniki sections.[8][9] The Tithorea–Domokos section was reconstructed on a partly altered route, shortening it from 121.60 km (75.56 mi) to 107.33 km (66.69 mi) in order to sustain high-speed railway requirements.[1] It includes two tunnels—the 9.3 km (5.8 mi) Kallidromo Tunnel, which is the longest in the Balkans, and the 7 km (4.3 mi) Othrys Tunnel.[10] Another upgrade is the reparation of the damaged electrification system of the section between Acharnes and Tithorea.[3]
An accident occurred near Tempi on February 28, 2023. It is Greece's worst railway disaster. The station master in Larissa was arrested in connection to the accident.[11]
