One of the drivers involved in the Spanish rail crash is under investigation claim Spanish media after suggestions the train was travelling at more than twice the speed limit.
Francisco Jose Garzon de Amo, 52, a train driver with 30 years experience, is to be questioned by police in hospital, the Galicia Supreme Court said in a statement after the accident which killed 78 people and injured more than 130.
Early investigations suggested the train was travelling more than twice the 80 kilometres per hour speed limit on a dangerous curve approaching the northern city of Santiago de Compostela in north western Spain.
All eight carriages of the Madrid to Ferrol train derailed on Wednesday evening, see previous story.
The service, from Madrid, was reportedly running late at the time.
Spain’s national train operator Renfe said that it was too early to say what caused the train to derail.
Spanish media published excerpts from Mr Garzon’s Facebook page, reports the Daily Telegraph.
In one posting, he was alleged to have said: "It would be amazing to go alongside police and overtake them and trigger off the speed camera." The comments were posted beneath a photograph of a train’s speedometer clocking 200 km/h."
The Galicia crash was one of the worst rail accidents in Europe in 25 years and comes less than a fortnight after six people died when a train came off the tracks and hit the platform at a station in central France.
