The Madrid-Andalusia high-speed rail line is set to reopen around 10 days after the investigating magistrate issues judicial authorization, following the fatal Urda collision on October 28, 2026, which caused 69 deaths. Spanish Transport Minister Óscar Puente confirmed that initial service will operate under a reduced timetable until the European Rail Traffic Management System (ERTMS) Level 2 signaling is fully operational.
The October 28 accident occurred amid a fault in the existing LZB signaling system at 08:31, leading to degraded operations under manual control. At 08:36, an Adif controller authorized AVE 2080 to proceed, but that train rear-ended the stopped
Iryo 6076 near Urda at 08:53, with collision speeds estimated between 160 and 200 km/h. The chain of technical failures and manual instructions proceeded without protective safeguards activating, according to Spain’s independent accident investigation commission (AITAT).
Thales, a French company contracted in December 2021 for about €98 million, is responsible for upgrading the Madrid-Seville line signaling systems, including the deployment of Level 2 ERTMS with a 52-month execution window. While Spain’s competition regulator CNMC approved the ERTMS replacement for 2025-2026, the Transport Ministry revised the timeline, now expecting completion in early 2027.
During the initial reopening phase, train operators Renfe,
Iryo, and Ouigo will face frequency reductions to accommodate ongoing infrastructure and signaling upgrades. Connections between Madrid and Andalusia remain suspended pending court clearance, while full train frequencies will not resume until after the comprehensive ERTMS installation. Adif has sought judicial permission to begin reconstruction and will supervise repairs over an extended 400-meter track segment despite direct damage to approximately 40 metres.
Minister Óscar Puente acknowledged the gravity of the Urda and the earlier Adamuz disaster, which claimed 46 lives nine and a half months prior. Puente emphasized Spain’s rail network’s international safety ranking but recognized the urgent need for
improvements. He also confirmed that clearance of derailed carriages is complete and pledged to restore passenger confidence through diligent safety enhancements.
Judicial inquiry into the Urda crash remains confidential, with the Civil Guard holding onboard train data recorders. The High Court of Justice of Castilla-La Mancha intervened to mandate increased crane contractor staffing to accelerate wreck removal. The Madrid-Andalusia line’s approach contrasts with the Madrid-Barcelona corridor, where planned works will maintain train operations without a service suspension.
