One avenue being investigated is the possibility that there were issues in one of the carriages at the rear of train as the doors didn’t close automatically. The guard was left standing on the platform. He had probably tried to close the doors from the outside. The train was on its way from Schaarbeek (Brussels) to the West Flemish city of Kortrijk.
The NMBS Spokesman Bart Crols told VRT Radio 2 East Flanders that "A number of witnesses saw the train depart without a guard”.
The train finally stopped at the next station in Ede, where another guard boarded to replace his stranded colleague .
"Passengers had to wait three quarters of an hour until a new guard was able to board the train”, Mr Crols added.
