It was an accident. You don't have any basis for thinking otherwise. Just because evil Martians could have derailed the train doesn't mean they did. There are about 11,000 rail accidents each year, from small to large. The fatalities range from 700 to 900 per year. You really need to abandon this "there are no accidents" superstition. Life is full of accidents. We are lucky there aren't more.
