40 Dead in Spain High-speed Train Crash 2026: Investigation Into Rail Fault Begins

Spain is reeling from its worst rail disaster in over a decade. A head-on collision has claimed at least 40 lives, prompting a promise of full transparency from the government.

On Sunday evening, January 18, 2026, two high-speed trains collided near Adamuz in southern Spain. A Madrid-bound train derailed and crossed onto the opposite tracks, striking an oncoming service heading south. Prime Minister Pedro Sánchez has declared three days of national mourning as rescuers continue to search the mangled wreckage.

The crash occurred at 19:45 local time on a straight stretch of track. Transport Minister Óscar Puente noted that most casualties were in the front carriages of the second train. While official findings aren't expected for at least a month, Reuters reports that investigators found a faulty joint on the rails, which may have caused a widening gap between sections.
