2011 Flores rail crash

The 2011 Flores rail crash occurred at 06.23 ART on 13 September 2011 when a bus on a level crossing at Flores railway station, in the Flores barrio of Buenos Aires, Argentina, was hit by a train on the Sarmiento Line, heading for Moreno. The accident caused that same train to collide into another one as it derailed.

It is regarded as the worst train accident in Buenos Aires within 50 years.

The train
The train, operated by Trenes de Buenos Aires, derailed and crashed into a second train, heading for Once in the Balvanera barrio, which was standing at the station. The accident, which occurred during the morning rush hour, resulted in 11 deaths and 228 injuries. The bus, owned by the company "Microomnibus Saenz Peña", was working a scheduled service on route 92, heading for Retiro.

Video evidence revealed that the bus driver, who was killed in the accident, ignored warning flash lights and bells on José Artigas street and drove around a partly lowered crossing barrier (partially due to the fact that these had been in a state of constant activation for some time).

Impact
The impact carried the bus into the station, where it was crushed against a platform, the majority of deaths were from people seated in the front of the bus, as this is where it was crushed against the platform. The front carriages of the train derailed, and hit the Once bound train, which was arriving at the opposite platform. It took firefighters two hours to release one of the train drivers from the wreckage. A total of 100 ambulances and 10 fire engines attended the incident, and some of the injured were ferried to hospital by helicopter. At the time, it was the deadliest rail crash within the city since the Villa Soldati level crossing tragedy in 1962.
