Rescue workers in Spain on Wednesday were scouring the wreckage for more bodies at the crash scene where at least 64 people were killed when two high-speed trains collided, in the second deadly railway accident in the country this year.

“We are speaking of approximately 64 (dead), but this is probably going to grow even more,” the leader of the central region of Castilla-La Mancha, Emiliano Garcia-Page, told reporters at the scene, raising a previous toll of 31.

Evacuated passengers streamed along a road near the scene, some splattered with blood or with their wounds bandaged, others wheeling suitcases and being given water by volunteers who said it had been donated from neighbouring towns.

Hundreds of ambulances, funeral home vans and helicopters were parked next to a train with several carriages sitting on an elevated section of track while twisted metal, broken panels and wreckage could be seen strewn across an embankment beneath the line where at least three carriages had plunged.

The accident comes after a collision between two high-speed trains in southern Spain in January resulted in the deaths of 46 people.

That crash in January, which occurred after a train derailed and smashed into an oncoming train near Adamuz, in Cordoba province, triggered a debate about the level of investment in railway maintenance in recent years.

“Traffic on the Madrid-Andalusia high-speed rail line has been suspended following a rear-end collision between two trains,” rail operator Adif said in a message posted on X on Wednesday.

A Renfe and an Iryo train crashed just after 9am (1pm PKT), causing two Iryo wagons to derail, a government spokesperson for the Castilla La Mancha region said, adding that the cause and number of injuries were still being determined.

Miguel, a passenger travelling with several colleagues in the rear car of one of the trains, described to COPE radio the moment of the accident.

“We heard a massive roar, a truly enormous thud that went on for 10 seconds, as if the train were about to derail. Through the right-hand window, we could see a wrecked train,” he said.

Adif said the incident occurred on the line from Madrid to Seville.

Manuel Galan, mayor of the nearby town of Urda, told Cadena SER that emergency services had asked the town council to prepare emergency facilities, including a sports hall, to accommodate passengers and the injured.

Prime Minister Pedro Sanchez’s agenda, published on the Spanish government’s website, had been cleared for the day. The opposition People’s Party also cancelled all campaign events, a spokesperson said.

PM Sanchez, who is seeking re-election next month, said he was “shocked” by the incident.

“Shocked by the serious train accident in Toledo,” Sanchez said on X about the incident south of Madrid, sending “my love, solidarity and support to all the victims and their families”.

PM Shehbaz Sharif said he was “profoundly grieved by the devastating train collision” and expressed his deepest condolences to Sanchez and the people of Spain.

“We pray for the speedy recovery of the injured. Pakistan stands with Spain in its hour of sorrow,” he wrote on X.

President Asif Ali Zardari also expressed deep sorrow over the train accident and extended heartfelt condolences to the bereaved families and sympathies to the injured.

“He expressed solidarity with the leadership and people of Spain in this difficult time and wished a speedy recovery to those injured,” according to a post on X from the President House.
