A train linking the Plaza Constitución station with the city of Bahía Blanca derailed this morning with 479 passengers on board. The accident occurred at 5:20 this morning, 10 kilometers south of the Buenos Aires town of Olavarría, and caused at least 20 injuries, none seriously, according to the company Trenes Argentinos y Bomberos.According to the mayor of Olavarría, Ezequiel Galli, 17 people, three of them with fractures, were transferred to the Municipal Hospital of the city. “None are seriously injured. Everyone is being taken care of by our health team,” he said. The rest of the passengers are being transferred to the Municipal Exhibition Center of Olavarría (CEMO) where they will receive the corresponding attention until they can restart their trip. ” The derailment occurred this morning, for reasons that are still being investigated, in the laying of tracks operated by the freight company FerroExpreso Pampeano.The process of routing and restoring the normal conditions of the tracks could take a few hours, so it is likely that some services that circulate through that corridor will be canceled.
