Germany’s Allianz and Australian group QBE bear the bulk of the insurance liability from this week’s fatal train crash in northwest Spain, Reuters reported, according to sources at the companies.While Allianz’s Spanish subsidiary covers a compulsory personal accident policy for Spain’s state-owned rail network Renfe, QBE covers injury to third parties and rail infrastructure, if the train operator is found to bear responsibility, the sources said.The train driver was under police guard in hospital following the crash, which an official source with knowledge of the investigation said was caused by excessive speed.The crash killed 78 people.The source at QBE said the firm has not yet produced an estimated insured loss from the accident as the cause of the crash remains unclear. According to previous statements, QBE says its exposure to any single public event is limited to $50 million under its reinsurance arrangements.
