Your train wreck is interesting, could be a simple accident or a planned one.......LOL, still don't know the answer.
The reference to the faulty switch caught my attention in the article. As we look back we can recall that many were stolen earlier in the year. I agree though...we can't really tell if it was an accident if it was planned.
We had another tanker accident with a chlorine spill on the highway system yesterday. They had to close down roads until cleaned up by Hazmat.
