Welcome to the official site of Transportation Safety Bureau of Hungary!


Transportation Safety Bureau of Hungary (TSB) is an independent investigating body what ensures that an investigation is carried out after any serious accident on the Hungarian rail system. According to Directive (EU) 2016/798 of the European Parliament and of the Council of 11 May 2016 on railway safety.

The activity of TSB is based on Act CLXXXIV of 2005 on the safety investigation of aviation, railway and marine accidents and incidents. TSB is independent in its organisation, legal structure and decision-making from any infrastructure manager, railway undertaking, charging body, allocation body and conformity assessment body and from any party whose interests could conflict with the tasks entrusted to TSB. Furthermore, TSB is functionally independent from the national safety authority, from the European Union Agency for Railways (ERA) and from any other regulator of railways.

Investigations are carried out independently of any judicial inquiry. Investigations are in no case concerned with apportioning blame or liability. The objective of an investigation is to improve, where possible, railway safety and the prevention of accidents.
