Lisbon Funicular Tragedy: Cable Failure Investigated After Deadly Derailment

Lisbon, Portugal – A preliminary investigation has revealed that a snapped connecting cable caused the devastating derailment of a historic funicular in Lisbon on Wednesday, resulting in a tragic loss of 16 lives and injuries to 21 others. The incident, which occurred on the Elevador da Gloria, is being described by officials as one of the worst tragedies the city has seen in recent memory.

What Happened on the Elevador da Gloria?

The Office for Air and Rail Accident Investigations released its initial findings on Saturday, indicating that the two carriages of the funicular traveled approximately 6 meters (20 feet) when the crucial cable connecting them suddenly failed. This loss of connection resulted in the upper carriage accelerating rapidly down the steep incline.

According to the report,the brakeman on the descending car instantly engaged both the pneumatic and hand brakes in an attempt to control the runaway carriage. However, these efforts proved unsuccessful, and the car continued its uncontrolled descent.

Investigators determined upon examining the wreckage that the connecting cable had broken at the point of attachment to the cabin positioned at the top of the hill. The Elevador da Gloria, a yellow-and-white funicular, navigates a sharply sloped street in Lisbon’s downtown area.

how Do Funiculars Work?

Funiculars, often mistaken for streetcars, operate using a unique cable system.They employ two carriages connected by a cable, where the weight of the descending car assists in pulling up the other. This system allows for travel on steep gradients impractical for traditional railways. the Elevador da Gloria is capable of carrying over 40 passengers at a time, both seated and standing.

The precise number of passengers on each carriage during the incident remains undetermined and is part of the ongoing investigation.

The incident severely impacted Lisbon public transport and raised concerns about the aging infrastructure of the city’s iconic tram system.

Key Findings of the Investigative Report

The complete report, released today, definitively links the derailment to the failure of a connecting cable within the streetcar’s braking system. Specifically:

Cable Fatigue: The investigation revealed significant metal fatigue in the cable responsible for activating the emergency braking system. Microscopic analysis showed repeated stress and corrosion, ultimately leading to a complete fracture.

Insufficient Maintenance: While regular inspections were conducted, the report criticizes the depth and frequency of these checks. the cable in question was not identified as being at risk during routine tram maintenance procedures.

Material Defect – Potential Issue: Investigators are also exploring the possibility of a pre-existing material defect in the cable itself, though this remains a secondary line of inquiry. Testing is underway to determine if the cable met required safety standards upon initial installation.

Braking System Failure: The fractured cable prevented the driver from engaging the emergency brakes effectively when navigating a steep descent, a crucial safety feature on Lisbon’s hilly streets. This led to a loss of control and the subsequent derailment.
