A train traveling from Uitgeest to Alkmaar experienced an explosion in its electrical cabinet, resulting in one injury and disruption to service. The incident occurred at approximately 8:18 PM on a double-decker VIRM train, the most common type in the Netherlands, carrying around 650 passengers.

The explosion, which originated in the electrical cabinet located on the train’s platform, caused a panel or door to strike a passenger in the head. The injured passenger was subsequently transported to a hospital. Three other passengers reported feeling unwell due to smoke inhalation.

Following the explosion, the train’s power was cut off, disabling the air conditioning and ventilation systems. Passengers reported that the carriages became excessively hot, likening the conditions to a car left in the sun. Doors were opened to provide fresh air.

An evacuation train was dispatched to transport passengers to Alkmaar station within an hour of the incident. Authorities believe the explosion was caused by a defect in the train rather than intentional action.

The train involved in the explosion had been modernized between 2014 and 2017. The electrical cabinet contained a “down chopper module” responsible for converting the overhead line voltage to the appropriate voltage for climate control and relay operation, which is crucial for railway safety.

Technicians are currently investigating the cause of the explosion. The Human Environment and Transport Inspectorate (ILT) will also be present to monitor the investigation and gather information. It remains unclear whether the ILT will conduct its own independent inquiry.

A spokesperson for the railway company emphasized that passenger safety is a top priority and assured the public that such incidents are rare. This type of event has never occurred before, and the trains are generally safe, the spokesperson noted.

The incident follows another unusual railway event last week, where a fire near the Schiphol tunnel damaged power cables and disrupted train traffic. Police suspect that the fire was a criminal act.
