In 1996, the Orfana bypass was opened. In 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. The Tithorea–Domokos section was reconstructed on a partly altered route, shortening it from 122 to 106 km in order to sustain high-speed railway requirements. It includes two tunnels—the 9.3 km Kallidromo Tunnel, which is the longest in the Balkans, and the 7 km Othrys Tunnel. Another upgrade is the reparation of the damaged electrification system of the section between Acharnes and Tithorea. The Piraeus–Platy railway is used by the following passenger services:
