At least four people were killed on Friday after a train derailed in northwestern Spain, emergency services in Galicia said.
Dozens of people were also injured in the crash, Spanish media said, citing Eva Garcia de la Torre, the mayor of O Porrino, the town closest to the accident.
The train was travelling from the Galician town of Vigo to the city of Porto in Portugal when the accident happened near O Porrino.
It was carrying 63 passengers and two crew members, including the driver, state-run railway operator Renfe said.
Spanish media reported the driver was among those killed.
Renfe said the train and the driver were both Portuguese, adding that railway traffic had been suspended in the area.
Television footage from the accident, which happened just before 9.30 am showed the train’s front carriage flipped onto its side and rammed up against an electricity pylon next to the track. The crash took place close to a station.
A spokeswoman for Adif, the company that manages railways in Spain and is in charge of the tracks, said: “It’s a very straight line.”
Pictures posted in local daily La Voz de Galicia showed doctors attending to passengers on the station platform.
Ramon Gonzalez, a witness interviewed by Spanish television, said there was a “very strong bang.”
“It was full of black smoke,” he said over the phone. “It’s a straight line… so this isn’t normal.
“There are still some injured here but very not serious, the seriously injured were quickly evacuated.”
In 2013, 80 people were killed in Spain’s worst rail disaster in decades when a high-speed train went off the tracks and slammed into a wall near Santiago de Compostela, in Galicia.
A pre-trial investigation of the July 24, 2013 crash carried out by a court in Galicia concluded the accident was caused by a lapse in attention by the driver, who was on the telephone at the time of the crash with another rail employee.
It was not immediately clear what had caused Friday’s crash.
