The incident resulted in injuries to up to four passengers, including one who sustained a head wound and was hospitalized. Approximately 650 passengers were evacuated following the explosion, which caused the train to halt. Initial investigations by the Dutch rail operator NS revealed that the explosion was caused by a defective component in the electricity cabinet.
