Spain train crash: attention focuses on driver, Francisco José Garzón

News agency reports Garz n telling emergency services: 'I hope there are no dead - they will be on my conscience. I want to die'

Several Spanish rail experts have voiced the opinion that mere negligence cannot explain Wednesday night's crash: that the "black boxes" recovered from the train will show that a technical fault was partly - or perhaps entirely - to blame for what happened. But the arrest of the driver, Francisco Jos Garz n, and a steady trickle of extracts from the transcripts of conversations he held immediately after the disaster have increasingly focused attention on his role.

While still trapped in the cockpit of his train, the Alvia 151, he is said to have told the emergency service of Spain's national rail company, Renfe: "I hope there are no dead, because they will be on my conscience." He also reportedly said over and again: "We're human."

The Spanish news agency Europa Press reported that during the same conversation, though it was not clear in what context, Garz n had said: "I've fucked it. I want to die."

His position also appeared to have been compromised by the emergence of a photograph he posted to his Facebook page showing his speedometer at 200km/h.. Garz n is, however, a driver of high-speed trains and he may have been on a stretch of the network where such a speed is permitted.

The photograph went up on 8 March 2012. Renfe's president, Julio G mez-Pomar Rodr guez, said Garz n had worked on the Ourense-Santiago line for more than a year. Before that, he was on the line between Madrid and Barcelona, which is served by so-called AVE trains that can reach speeds of 310km/h.

The photograph nevertheless surprised Garz n's friends. One wrote: "You're going like the bloody clappers, lad. Brake." The driver replied: "I'm at the limit. I can't go faster, otherwise they'll fine me."

The photograph and the exchange of messages on Garz n's Facebook page disappeared early on Thursday morning.

The driver of the ill-fated train was born 52 years ago in Monforte de Lemos, a town 70 miles inland from Santiago de Compostela. It was there that he began work for Renfe in his early 20s.

It was not until 2003, however, that he became a driver. Spain's high-speed railway network was a prime symbol of the country's prodigious economic growth after joining the European Union in 1986 and, like the other drivers on the network, Garz n is well qualified and regularly evaluated.

To be licensed for the AVE trains, or the slower but still fast Alvias, drivers must have either a higher technical diploma or the academic qualifications for university entry. They have to have spent at least four years driving conventional trains.

They then have to pass a special exam that includes tests designed to show that they are physically and psychologically fit for the job. Even if they pass, they are entrusted with a train only after having demonstrated that they have a full understanding of how it works and the line that it plies. AVE and Alvia drivers, moreover, must renew their licences every three years.

Garz n asked to be transferred to his native Galicia in Spain's north-west because, he said, he wanted to be able to spend more time with his sick mother. But it was his mother who was at the train driver's hospital bedside on the Thursday night as police, acting on orders from the investigating magistrate, stood guard nearby.
