On 18 January 2026, a high-speed passenger train derailed in the municipality of Adamuz, in the province of Córdoba, Spain.^[2] The derailment occurred on a straight section of the track that was last refurbished in May 2025.^[1] A second train crashed into it and was also derailed. The incident killed 45 people and injured 292 others, including 15 in critical condition.^[3] The crash was Spain's worst railway disaster since the Santiago de Compostela derailment in 2013,^[2][4] and the fourth deadliest railway accident ever recorded in the country.^[5]

Spain's high-speed rail network is the second longest in the world, behind China's.^[6] Fatal derailments have occurred on the network, most notably the Santiago de Compostela derailment in July 2013 that killed 79 people. The Madrid–Seville high-speed rail line has been operational since 1992.^[7] Since 2014, the line has been operated by the state-owned infrastructure operator ADIF–Alta Velocidad.^[8] Renfe-Operadora, Spain's state-owned national train operator, was created in 2005 as a successor to the long-established Red Nacional de los Ferrocarriles Españoles.^[9] ILSA, a rail company majority-owned by Trenitalia, was founded in 2019,^[10] and began offering services in Andalusia in 2023 under the brand Iryo.^[11]

The Sindicato Español de Maquinistas y Ayudantes Ferroviarios (SEMAF), a train drivers' union, warned railway operator ADIF in August 2025 of heavy wear and tear on tracks, including where the derailments happened. This included potholes, bumps, and imbalances in ​overhead power lines that were causing frequent breakdowns and damaging ‍the trains. Allegedly, no action was taken despite the warnings.^[12][13]

High-speed trains between Madrid and Andalusia have experienced frequent delays since 2022. At least 18 incidents have been reported on the tracks over the past three years, from signalling failures to issues with overhead lines. Spain's high-speed network is particularly vulnerable to cable thefts, as it crosses large swathes of sparsely populated countryside.^[12]

The eight-car Iryo 6189, trainset 109–012, had departed Málaga María Zambrano station for Madrid Atocha station at 18:40 CET, while the four-car Renfe train, Alvia 2384, had departed Madrid Atocha at 18:05 bound for Huelva–Las Metas station [es] in Huelva.^[2][14] The Iryo train, travelling northbound with 289 passengers and 5 crew members on board, left its scheduled stop at Córdoba–Julio Anguita station at approximately 19:39.^[15]

At 19:43,^[16] passing through the municipality of Adamuz, its three rear carriages derailed and invaded the opposite parallel (southbound) track, while the front of the train continued on the original (northbound) track.^[2] The Renfe train, travelling southbound on the parallel track with 184 people on board, collided with the derailed Iryo train about 20 seconds later and also derailed.^{[17][3][18][2]} The Renfe train sustained more severe damage, with its first two carriages falling down a 4 m (13 ft) embankment.^[19]

The derailment occurred on a straight section of track that was last refurbished in May 2025.^[1] Both trains were travelling within the 250 km/h (160 mph) speed limit on the track.^[20] Access to the site of the derailments was through a single-lane road, complicating rescue and recovery operations.^[21]

Forty-five people were killed,^[22] and 292 others injured. Of the injured, 170 were treated for minor injuries and 122 others, including 15 in critical condition, were transported to hospital. By the following day, 79 people had been discharged.^[23] Among those killed in the crash was the driver of the Renfe train.^[24] Efforts were also made to find a missing dog that was traveling on the Iryo train with its owners. The dog was found alive on 22 January by forest firefighters.^[25]

Óscar Puente, the Minister of Transport and Sustainable Mobility, described the crash as "tremendously strange". He said that it occurred on a section of track consisting of "a straight line" that was renovated in May 2025, and that €700 million had been invested in that section of track, which was "supposedly in perfect condition".^[17] The Iryo train that derailed was described as "relatively new":^[26] it was manufactured in 2022 and passed its last safety inspection on 15 January 2026.^[27][2] The first investigations pointed towards a faulty rail weld as a possible cause of the crash,^[28] and a report published on 23 January confirmed that, as a working hypothesis, a 40-centimetre (16 in) break in a rail was the focus of the investigation. Investigators inspecting the wheels of the Iryo cars that did not derail observed a specific pattern of damage:

• Only the right wheels (looking in the direction of the traffic) were damaged
• On cars 2, 3 and 4, wheels belonging to the first wheelset of each bogie bore marks consistent with hitting a "cliff" in the rail at the point where it was broken.
• Wheels belonging to the second wheelset of bogies had no marks, because the weight of the first wheelset had depressed the rail forward of the break, temporarily making it flush again with the section before the break. Investigators estimated the time between two wheelsets passing at the relevant speed as 30 milliseconds, insufficient for the rail to spring back.
• On car 5, the pattern differed from the previous one, with impact marks visibly displaced toward the wheel's edge. Investigators hypothesize the rail had started to rotate outward.
• Car 6 was the first to derail. The wheels of the derailed carriages where found too damaged by impact with ballast to immediately interpret.

A section of rail was found after the crash to bear marks on its side, described as consistent with one or more wheels having passed on it as lay sideways.^[29]

Three trains had travelled along the line before the derailment occurred. All three sustained damage to their wheelsets.^[30]

A makeshift hospital was set up at a sports centre in Adamuz to treat the victims.^[15] The Civil Guard confirmed the suspension of high-speed rail service between Madrid and Andalusia for 19 January,^[3][31][32] which was subsequently extended until 23 January.^[33] It also opened offices in Córdoba, Madrid, Málaga, Huelva, and Seville for relatives of the missing and unidentified deceased to deliver DNA samples for identification.^[15] The stations of Madrid-Atocha, Córdoba–Julio Anguita, Seville–Santa Justa, and Málaga–María Zambrano remained open all night 18 to 19 January to accommodate the hundreds of passengers who could not take their scheduled trains.^[34] Iberia airline increased flights to Seville and Málaga to assist stranded travelers.^[15]

Two days after the derailments, another commuter train hit a collapsed wall, derailed, and crashed in Gelida, Barcelona, killing the driver and injuring 37 others.^[35] The derailment was believed to be caused (in part) by heavy rainfall that swept across the region this week as a result of Storm Harry,^[36] compromising the structural integrity of the wall.^[37] In response to the series of accidents starting with Adamuz, Spanish trade union SEMAF called for a three-day strike to take place in February 2026.^[38]

Prime Minister Pedro Sánchez said that the government was working with emergency services to help those affected, while Andalusian regional president Juanma Moreno expressed both his concern and support for the victims and their families. The infrastructure manager of the line ADIF said it would establish spaces for relatives of victims at Atocha, Seville, Córdoba, Málaga, and Huelva stations.^[1]

The defence ministry said it would deploy 15 vehicles and 40 personnel from the Military Emergencies Unit to the site of the derailment.^[39] Sánchez declared three days of official mourning,^[40] beginning on 20 January,^[21] and cancelled his scheduled visit to the World Economic Forum in Davos, Switzerland, in order to visit the crash site.^[41] King Felipe VI and his family, who were in Greece for the funeral of Princess Irene, expressed their dismay and solidarity with the victims and cancelled their schedule for 20 January to visit the crash site.^[42]
