In January 2026 a train derailment in Adamuz, Spain, caused by rail infrastructure deficiencies, killed 46 people.

Omissions

• The toll of 46 was reached only on 30 January 2026, when a hospitalized woman died; the initial official count given by the Ministry of Transport on 20 January 2026 was 40 fatalities, and El País/Reuters reported 45 by 22–23 January.
• The event was a derailment followed by a collision with an oncoming Alvia train on the adjacent track; many of the deaths resulted from that collision rather than the derailment alone.
• The cause attribution ('rail infrastructure deficiencies') reflects the prevailing preliminary hypothesis of the investigation (a break/failure in the track, 'rotura en la vía', with human error ruled out), but the investigation was still open and alternative hypotheses (e.g., an element detaching from the train) were also being considered.
• No primary official source confirming the final figure of 46 was found; the final toll is corroborated by two public broadcasters (RTVE and RTVC), which may both draw on the same agency/official reporting.
