[1] It is regarded as the worst train accident in Buenos Aires within 50 years,[2] though its death toll would be surpassed six months later by another crash in the city center.

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).

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.
