Madrid, Sept. 9 (Reuters): At least four persons died and close to 50 people were injured on Friday after a train derailed in Galicia in north-western Spain, local authorities said.

The train driver, a Portuguese national, was among those killed, according to authorities in the Galician town of O Porrino, the nearest to the accident. Another crew member and 63 passengers were on board the train, which crashed close to a station around 20 minutes into its journey between the Spanish city of Vigo and the Portuguese city of Porto.

Regional authorities said 47 people were taken to hospital.

Television footage from the accident, which happened just before 0730 GMT, showed the train's front carriage flipped onto its side and rammed up against an electricity pylon next to the track.

Spain's state rail manager Adif said it had launched an investigation into the causes of the accident.
