Spain's Transport Minister Óscar Puente resigned on Tuesday after two deadly train crashes killed 115 people in less than a year.

The latest disaster occurred on October 28 near Urda in Toledo. Two high-speed trains collided, killing 69 people and injuring more than 200. Another collision in January near Adamuz in Córdoba killed 46. The January crash involved the same companies on the same Madrid-Seville line. Together, the accidents have left 115 dead.

Puente announced his resignation at the end of a four-hour hearing before the Permanent Deputation of Congress. "A transport minister in a country like Spain cannot remain in office after two accidents of this severity in less than a year," he said. He also withdrew from the November 29 snap election, saying he would not stand as the Socialist Party's lead candidate for Valladolid.

In the Urda collision, a signaling system failure stopped several trains. A controller at Adif's Madrid control center authorized a Renfe train to proceed despite a stationary Iryo train ahead. Investigators estimated the impact speed at 160 to 200 kph.

Before resigning, Puente outlined emergency measures. Services on the Madrid-Seville line will be reduced until safety reviews are complete. The government will impose a 40 kph speed limit when drivers must spot obstacles ahead after a signal failure. It will hire more control center staff and introduce an AI agent to monitor conversations between drivers and controllers. Puente said the AI system would be a world first. The government also promised to double compulsory passenger insurance payouts and speed up compensation.

Opposition parties PP and Vox demanded Puente's resignation. Several government allies, including Sumar, ERC and the PNV, also called for him to leave. On the day of the Urda accident, more than 1,000 demonstrators in Madrid called him a "murderer." A poll by El Mundo found 66 percent of respondents wanted him to resign.

Prime Minister Pedro Sánchez praised Puente on X, thanking him for putting victims first. Puente said he informed Sánchez of his decision minutes before announcing it. Puente described his resignation as a matter of "political dignity," adding it was the right call for "a modern country, not a failed state as some claim."

Puente, a close ally of Sánchez, had served as transport minister since 2023. His resignation comes less than four weeks before the November 29 election. Sánchez called the snap election after parliament rejected housing reforms. Puente had previously ruled out resigning. He said he decided to step down within minutes of learning of the October 28 crash but stayed until emergency measures were in place.
