Fact is, derailments happen all the time. But on rare occasion they are spectacularly bad, and then the media focuses on each and every one they can find. They are costly for the railroads and they really do try to prevent them. Did you know… when a train is stopped in a siding while waiting for an opposing train to come by, a crew member is required to leave the cab and stand trackside to inspect the passing train for defects and problems?
