At Sittard, a sidewalk tile was thrown from an overpass onto an intercity train, ProRail reports. The rail manager writes on Twitter that the driver heard a loud blow.
No one was injured in the incident. A wiper broke off the train. ProRail calls the promotion life-threatening.
Last Friday two boys of 15 years were arrested, after they had fired at two trains on the route between Tilburg and Breda with ball guns with metal balls.
