It takes a lot of trash on the tracks to derail a train. Trains frequently just run over downed trees because clearing them would involve hours of waiting and it rarely does any damage of note. Maybe if the trash is scrap steel you might have a shot.

It's pretty likely that the derailment is a switching failure because the train is riding on two different tracks. If it was just dragging along on the ties and rail bed that would be more indicative of some other kind of derailment.
