The YouTube channel "German in Venice" was there today and asked one of the train workers which told him the derailment was not caused by the trash. Looking at another video on Twitter where the train is riding on both tracks it appears and railway switch failed halfway while the train was running over it. I saw this happen to a light rail here in Zürich during a very cold day, the railway switch snapped back in the middle of a railcar running over it. One track turned up another street so the railcar ripped apart at the flexible junction. Of course a piece of trash could easily have caused the failure of the railway switch.
