Multiple switch failures disrupted train services between Rotterdam and The Hague overnight, with investigations underway to determine the cause. ProRail officials stated that the issues occurred in areas where no work was being conducted. Train traffic faced significant delays, with services completely halted in the morning before gradually resuming in the afternoon. This incident follows a weekend of major rail works between the two cities, which had already affected transportation. The final switch issue near Delft is expected to be resolved soon, with findings from the investigation anticipated in the coming days.
