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.
