Accident ISI

The ISI or Infrabel Safety Indicators are a tool for monitoring the evolution of railway safety and for setting internal safety objectives.
They include the relevant accidents, i.e. any accident involving at least one moving railway vehicle, the consequences of which are at least one death or a seriously injured person, or relevant damage to rolling stock, track, other installations or the environment or major traffic interruptions. Accidents in workshops, warehouses and depots are excluded.
