LISBON — A preliminary investigation into the September 3 crash of Lisbon’s iconic Glória funicular suggests that a faulty cable may have triggered the accident that killed 16 people and injured 21 others.
Experts cited by Portuguese newspaper Expresso said the original steel cable had been replaced with one composed of six steel strands surrounding a fiber core.
Over time, the fiber core became deformed, and the differing physical properties of the materials may have led to overheating from friction and vibration, ultimately causing the cable to snap.
The funicular, which operates by connecting two cars with a cable—one ascending as the other descends—lost control while traveling down the steep Calçada da Glória. It derailed in a curve and crashed into iron posts and a building. Investigators also noted that oil on the tracks may have contributed to braking failure.
The findings are based on early assessments, and a full report from Portugal’s accident investigation bureau is expected in the coming weeks,
