Cable Failure Identified as Cause of Deadly Lisbon Funicular Crash

A preliminary investigation into the fatal funicular crash in Lisbon has determined that a cable connecting two cabins snapped, leading to the accident that claimed 16 lives, including 11 foreign nationals.

The Office for Air and Rail Accident Investigations reported that the cable detached at its attachment point to the upper cabin shortly after the journey began. Despite the brakeman's efforts to apply both pneumatic and hand brakes, the descending cabin accelerated uncontrollably, resulting in the derailment.

The cable had been in use for 337 days out of its specified 600-day lifespan and had passed a visual inspection on the morning of the accident. However, the section where the cable failed was not accessible for visual inspection.

The crash occurred on Wednesday, September 3, 2025, at around 6 p.m., when the funicular, a popular tourist attraction, derailed and collided with a building. The victims included five Portuguese citizens and 11 foreigners from countries such as the United Kingdom, Canada, South Korea, the United States, France, Switzerland, and Ukraine.

In response to the tragedy, the Portuguese government declared a national day of mourning, and Lisbon's City Council announced three days of municipal mourning. Mayor Carlos Moedas described the incident as "a tragedy the likes of which we've never seen in this city."

Investigations are ongoing, with authorities aiming to provide a comprehensive final report detailing the causes of the crash.
