Adamuz rail crash investigation remains open nine months later
On 18 January, an Iryo high-speed train derailed near Adamuz in southern Spain and struck a Renfe train heading to Huelva.
The crash killed 46 people and injured more than 100, and the investigation is still open nine months later.
Investigators are examining a suspected break at a rail weld joining sections installed in different years, with signs of material fatigue.
They are also checking whether earlier signs of damage were missed and whether the ballast or sleepers contributed.
The inquiry is testing whether inspection and maintenance systems could have prevented the crash, as well as what caused the rail to break.
A separate judicial investigation will consider whether any actions or omissions had criminal significance.
The crash has prompted wider concern about rail safety in Spain, but the available evidence does not establish that the network is generally unsafe.
Technical investigators are expected to determine the causes and recommend steps to help prevent another accident.
The Adamuz train crash killed 46 people and injured more than 100, and its investigation remains open nine months later.
On 18 January 2026, an Iryo high-speed train travelling from Málaga to Madrid derailed and entered the adjacent track, where a Renfe Alvia train was travelling to Huelva.
Investigators are examining a suspected rail fracture at a weld joining sections installed in 1989 and 2023, with signs of material fatigue reported.
Authorities have not yet determined why the rail broke, whether there were warning signs or whether inspections could have detected the problem.
The crash prompted debate over railway safety, infrastructure maintenance and oversight in Spain.

What people are saying
Hemos llegado a normalizar lo que es un riesgo para todos y todas
There are more trains on the network, but all this is well taken into account in the engineering prescriptions for the track and safety systems. For me, competition is not to blame.
If we want solid infrastructure that can support many train movements, because rails wear out like any infrastructure, they need to be replaced and properly maintained.
