Athens Airport – SKA – Kiato – Patras railway

New double track from the Acharnes Railway Centre (SKA) to Athens Airport at Spata, between the two carriageways of the Attiki Odos motorway, with signalling, remote control and electrification, as part of the Athens suburban railway. ERGOSE gives 32 km, funding of EUR 240 million from the Third Community Support Framework and EUR 60 million from national resources (no total cost is stated), design speed 140 km/h to Doukissis Plakentias and 160 km/h beyond, and nine stops (Metamorfosi, Irakleio, Nerantziotissa, Kifisias, Pentelis, Doukissis Plakentias, Pallini, Kantza, Koropi); Greek Wikipedia gives 33 km and dates the start of work to January 2002. The Doukissis Plakentias – Airport stretch is also used by Metro Line 3, a line not recorded in this dataset.

New double track from the Acharnes Railway Centre (SKA) to the new Kiato station, with ETCS signalling, telecommunications and electrification. ERGOSE lists 5 tunnels of about 8,264 m in total, 4 cut-and-cover sections of about 1,401 m, 21 railway bridges, 60 grade-separated crossings, 8 stations (Ano Liosia, Magoula, Nea Peramos, Megara, Kineta, Agioi Theodoroi, Corinth, Kiato) and 3 stops (Thriasio, Zevgolatio, and the new Zefyri stop, handed over to OSE in July 2017). Construction began in 1998, SKA – Corinth was handed over in 2005 and Corinth – Kiato in 2007; the line was in full operation with electric traction from December 2010. ERGOSE gives a design speed of 200 km/h beyond Thriasio and a travel time of 60 minutes, down from 110.

New double track from the new Kiato station to Rododafni, beyond Aigio station, with ETCS level 1 signalling and telecommunications. ERGOSE lists 6 tunnels of about 11,000 m in total, 8 escape tunnels of 2,150 m, 13 cut-and-cover sections of 1,710 m, 18 railway bridges, 3 stations (Xylokastro, Akrata, Aigio) and 6 stops (Diminio, Lykoporia, Lygia, Platanos, Diakopto, Elikis); design speed 200 km/h for Kiato – Lykoporia and 150 km/h for Lykoporia – Rododafni. Construction began in 2006 and ERGOSE planned completion for 2019; Greek Wikipedia gives handover on 22 June 2020, and the Diminio stop opened in September 2020. Electrification of the 70.6 km is a separate ERGOSE contract (no. 1511), signed on 6 July 2022 with a TERNA – Mytilineos joint venture for EUR 54.82 million excluding VAT, with two traction substations at Xylokastro and Aigio; ERGOSE planned 2022–2025 and Greek Wikipedia gives a contract deadline extended on 11 December 2025 to 28 December 2026. It runs on track this lot already measures, so it is not a lot of its own.

Infrastructure of the new double track from chainage km 91+500 to km 113+000 between Rododafni and Psathopyrgos, including the Panagopoula twin tunnel (two bores of about 4,800 m with cut-and-cover ends, cross-passages every 500 m and an intermediate access tunnel of about 500 m), 3 railway bridges and 27 grade-separated crossings. ERGOSE lists the infrastructure contract as completed in 2022 for EUR 315 million. The line is not yet in service: track, signalling, electrification and stations over 28.8 km from Rododafni to the cut-and-cover after the new Rio stop (this lot and the first part of Psathopyrgos – Patras) are in ERGOSE contract 1510, signed on 22 November 2022 with a TERNA – Mytilineos joint venture for EUR 125.76 million excluding VAT, planned for 2022–2025. Greek Wikipedia gives a contract deadline extended from 22 November 2025 to 1 December 2026 and estimates that the line will reach only Psathopyrgos by then; no opening date is recorded for this lot. The contract value is not recorded as this lot's cost because it also covers part of the next lot.

Infrastructure of the new double track from Psathopyrgos to the Bozaitika area near Patras: formation of about 10.5 km, 2 cut-and-cover sections of 1,018 m in total (Agios Vasileios 625.97 m and Rio 392.20 m), 10 grade-separated crossings and 4 railway bridges of 60 m in total, design speed 100–120 km/h. ERGOSE gives the start of construction as 2017, planned completion in 2020 and an estimated cost of EUR 117 million, and its page lists the work as under construction. Greek Wikipedia states that the infrastructure from Psathopyrgos to Rio was started in 2017 but never completed and expects delivery of this stretch in 2028 (statement without a citation). Track, signalling and electrification of the first part, up to the cut-and-cover after the Rio stop, are in contract 1510 (see the previous lot). The drawn line measures only the part carried in OpenStreetMap.
