To be honest, I don't see what the big deal is. These kinds of things happen sometimes. It was hardly a major incident, so there isn't much to discuss.
True. However, that derailment actually involved a VIA train. Sure, it was empty at the time, but it was still something unusual and noteworthy. As for this one, I'm afraid I really don't get what the big deal is. Perhaps the original poster could explain why he feels it was so noteworthy. Also, the title of this thread is a little misleading.
I hope there won't be threads popping up each and every time CN has a minor derailment. This forum couldn't handle that sort of overload.
