The trains in Drenthe, Groningen, Drenthe and Friesland are running again according to the timetable. The NS and Arriva report this.
Train traffic was halted yesterday morning due to storm Poly. Cleanup crews worked through the night to clear the track and repair the damage
The NS reports that trains may be shorter than usual because not all equipment is in the right place when the train service starts. This can lead to more crowded trains than travelers are used to.
