If not strictly necessary, do not travel!
In the Netherlands, the timetable for public transport has been radically adjusted. All carriers now operate on a holiday or Sunday timetable or on a special basic timetable. The timetable will also be further adjusted in a number of regions in the coming days.
Public transport continues to bring people in vital functions to work. So don't go with public transport if this is not strictly necessary! Be well prepared and plan your trip shortly before departure for the most actual advice. Keep distance (at least 1.5 meters) and give each other space when getting in and out.
