Overview
- San Sebastián’s TAV station works were declared complete in mid-December, with the facility operating but central high-speed platforms idle until trains begin running.
- Irun’s new terminal remains under construction, with a phased reopening expected and full operation reported as likely by next summer, while through-connections to Burgos and Madrid via Arkaute are not anticipated before 2032 and there is no timetable for a French high‑speed link.
- Completion of the Gaintxurizketa tunnel in November restored double track between Lezo and Irun and lifted Gipuzkoa Cercanías frequencies by 27% to 47 daily services.
- The third‑track works between Astigarraga and Irun are scheduled to finish by late 2026, with a final summer 2026 shutdown and normal commuter traffic projected for late 2026 or early 2027.
- In Valladolid, Adif has formally terminated the 2017 integration agreement, prompting legal challenges from the city council and the regional government as station and freight‑variant works continue, with the public‑private society carrying roughly €420 million in liabilities.
