P.A.Th.E./P.

P.A.Th.E./P (Greek: Π.Α.Θ.Ε./Π., Πάτρα - Αθήνα - Θεσσαλονίκη - Ειδομένη/Προμαχώνας), which stands for Patras–Athens–Thessaloniki–Idomeni/Promachonas is a higher-speed rail line in Greece which is partly completed and partly under construction. The section between Athens and Thessaloniki was completed in 2019 and allows a theoretical minimum travel time of 3 hours and 20 minutes, although that has never been achieved in regular service. The line was significantly damaged by Storm Daniel in July 2023, and as of January 2026 is still undergoing extensive repairs.
