Reuters could not establish how far the initial investigation into what caused the bridge to collapse has proceeded but Mexico City Mayor Claudia Sheinbaum told reporters last week it would be completed in five weeks. Responding to questions from Reuters, Alstom said the consortium was "led by ICA" and that its role was "limited to power supply, signaling, monitoring and control systems and some depot equipment, as well as testing and commissioning of some electromechanical and track-work-sub-systems."Īlstom did not address what Carso's role had been. Carso's section included where the track fell by the Olivos station, according to the undated document. ICA also shared another document with Reuters with a graphic showing it had built sections of Line 12 spanning 15 stations, and Carso five. The official declined to comment further. It also declined to comment on the potential consequences of the investigation and has not publicly said which parts of the rail line it built.Ī spokesman for Slim, Latin America's wealthiest man, declined to comment on questions about Carso's work on Line 12.Ī Metro official shared with Reuters a screenshot of an undated Metro document titled "general characteristics of the line" that showed Carso built the section.

The city's investigators said they will be accompanied by Norwegian external auditor DNV in determining what happened on Line 12, built by a consortium of Mexico's ICA, Slim's Grupo Carso and French trainmaker Alstom.Ĭarso declined to comment on whether it had erected the section that collapsed. Mexico City's public works department declined a Reuters request for comment or an interview with Esteva, but said his comments to Grupo Formula were correct. "That's the information provided to us by the Metro." "The information we have is that it is Carso," Esteva told Mexican radio station Grupo Formula earlier this month. The head of Mexico City's public works department, Jesus Esteva, identified Carso as the contractor in charge of the section where the accident happened.

Inquiries will reach "wherever the investigation led" a spokesman for the attorney general's office told Reuters, when asked if that included the builders.
