The Transportation Safety Board (Junta de Seguridad en el Transporte - JST) of Argentina requested technical assistance from the ATSB to support its investigation into the collision between 2 trains on the railway bridge over Figueroa Alcorta Avenue, Palermo, Buenos Aires, that occurred at about 1030 local time on 10 May 2024.
Passenger train 3353 and work train T3021 were both operated by the State Railway Operating Company. Train 3353 was made up of locomotive B951 and 7 passenger cars. The T3021 work train consisted of locomotive 1000 and one car without passengers. The collision resulted in damage to the track infrastructure and rolling stock. It was reported by the JST that there were about 90 injuries among passengers and railway personnel.
To facilitate this support and to provide the appropriate protections for the information, the ATSB commenced an investigation under the Transport Safety Investigation Act 2003. At the request of the JST, the ATSB provided feedback in September 2024 on their preliminary investigation report. No further requests for follow-up assistance have been received. The ATSB's support to the JST has now been completed.
The JST is responsible for the investigation and release of the final investigation report regarding this accident. Once completed, a copy of the report can be accessed here.
