The China Mail - Barcelona train crash kills 1 in Spain's second deadly rail accident in days

The latest incident is likely to raise more questions about Spanish transport safety, coming two days after the collision of two high-speed trains in the southern region of Andalusia killed 42 people -- the country's deadliest rail accident in more than a decade.

On Tuesday, "a retaining wall collapsed onto the tracks, causing an accident involving a passenger train" in the municipality of Gelida, around 40 kilometres (25 miles) west of Barcelona, the Catalonia region's civil protection agency posted on social media.

The northeastern region's Interior Minister, Nuria Parlon, told local media the crash killed one person and injured 37 -- several seriously.

"We regret to announce the death of one of the passengers on the train," said Parlon, adding authorities had not yet completed the identification process of the deceased.

"Of the total number of people treated, five are in serious condition," she added.

Emergency workers used torches to survey the wreckage of the derailed train carriage, which had turned into a mass of crumpled metal, an AFP reporter saw on Tuesday night.

Spanish rail infrastructure operator Adif said a storm caused a wall to fall, creating the rubble that the train slammed into. Catalan commuter trains would remain suspended, it added.

Earlier on Tuesday, Spain's king and queen visited the site where two high-speed trains collided on Sunday as well as survivors of the accident that injured more than 120 people, 37 of whom are still in hospital.

The country's deadliest rail accident in more than 12 years took place when a train operated by rail company Iryo, travelling from Malaga to Madrid, derailed near Adamuz in the southern Andalusia region.

It crossed onto the other track, where it crashed into an oncoming train heading to the southern city of Huelva, which also derailed.

Dressed in dark clothing, King Felipe VI and Queen Letizia shook hands with emergency services workers near the spot where the mangled wreckage of the trains lay.

They then visited a hospital in the nearby city of Cordoba, where some of the injured are being treated.

Speaking to reporters after leaving the hospital, Felipe said he wanted to "convey the affection of the entire country" to the victims.

Santiago Salvador, a Portuguese national who broke a leg in the accident, said he felt lucky to be alive.

"I was thrown through the carriage; it felt like being on a carousel," Salvador, his face covered in cuts, told Portuguese state television RTP.

"It looked like hell. There were people who were very seriously injured."

- Crack on tracks -

Sunday's derailment was Spain's deadliest rail accident since 2013, when 80 people were killed after a train veered off a curved section of track outside the northwestern city of Santiago de Compostela.

Flags flew at half-mast on public buildings, television anchors wore black, and cabinet ministers curtailed public appearances as Spain observed the first of three days of national mourning.

The government has vowed a full and transparent investigation into the cause of the accident.

Unlike the 2013 disaster, the derailment occurred on a straight section of track, and the trains were travelling within the speed limit of 250 kilometres (155 miles) for the area concerned, officials said.

Spanish media report that the probe is focusing on a crack more than 30 centimetres (12 inches) long in the track at the site of the accident.

The crack may have resulted from "a poor weld or a weld that deteriorated due to train traffic or weather", daily newspaper El Mundo reported, citing unidentified technicians with access to the inquiry.

Transport Minister Oscar Puente said investigators were looking to see if a broken section of rail was "the cause or the result" of the derailment.

He said the Iryo train was "practically new" and the section of track where the disaster happened had been recently renovated, making the accident "extremely strange".

- Sabotage ruled out -

Interior Minister Fernando Grande-Marlaska said "the possibility of sabotage was never considered" and that "there has never been any element suggesting otherwise."

The head of state rail operator Renfe, Alvaro Fernandez Heredia, said human error has "been practically ruled out".

Maintenance crews will inspect the tracks overnight, and the restriction is expected to be lifted if no issues are found, the company added.
