Investigators added that the brakeman of one of the carriages applied the brakes, but that this didn’t have sufficient capacity to prevent the disaster.
Both carriages had travelled only six meters after leaving their stations on Wednesday, around 6 p.m., when the cable connecting them snapped, the report said.
Sixteen people died in Wednesday’s crash, among them 11 foreigners: five Portuguese, two South Koreans, one Swiss, three Brits, two Canadians, one Ukrainian, one American and one French.
Lisbon is holding local elections next month, with incumbent Carlos Moedas, a former European Commissioner, seeking a second term.
