In the railway field, the TSB investigates any occurrence related to the circulation of a vehicle that causes both death and serious injury to people and serious damage to rolling stock, railway infrastructure and the environment. In addition, it will also intervene in case of collision or derailment, as well as fire, spillage in the rolling stock or in the railway infrastructure, provided that all of them happen within the territory of the Argentine Republic. Once the process of investigation and analysis of the event is concluded, TSB performs the control of the safety measures implemented.
