Greece plans final rail section to the port of Patras

The planned roughly 8.5 km extension would continue the existing Athens Airport–Kiato/Rododafni line from Kastelokampos via the Trion Simmachon/Agios Andreas station to the new port of Patras, with 5.2 km running underground across 9 planned stations. A December 2020 press report estimated costs at around EUR 514 million, and a January 2024 newspaper report cited 2029 as the target year. Per Wikipedia, this final section still lacks a finalized project definition, agreement with local authorities, and secured funding, while the preceding Aigio–Psathopyrgos (target 2026) and Psathopyrgos–Rio (target 2028) sections are further along. Update (23 Mar 2026): For the route through Patras, the government in Athens and the infrastructure manager OSE have, according to regional media, proposed a tunnel of only 1.5 km under the city centre; more than 10 km had originally been planned, and the European Commission had repeatedly refused to fund earlier variants. The standard-gauge line would run as far as a former industrial site near the port that is now controlled by the port authority and is to become a freight centre. The regional representative is cautiously optimistic while the city rejects the proposal; in December 2025 a tram above underground long-distance rail had also resurfaced as an idea. There is no end to the dispute in sight. (LOK Report, 11 Dec 2025 and 23 Mar 2026)
