Investigators state this in a preliminary report on the accident, where they also note that the maintenance work has been deficient.
All of Lisbon's funiculars have been out of service since the accident and according to the investigators, they should remain still until checks confirm that they have "braking systems that can immobilize the cars in the event of a cable break".
It was on September 3 that the Glória funicular's cars suddenly ran away and crashed at the square below. The accident occurred at 60 kilometers per hour and the entire process was over in 50 seconds.
Eleven of the sixteen fatalities were foreign nationals, including three Britons, two Canadians, and two South Koreans. Around twenty people were also injured.
