I'm so very, very thankful that the derailment yesterday wasn't any more serious, and that no injuries resulted.
But if you remember back a few weeks ago, I suggested here the need for an emergency response plan to be prepared an in place.
I'm not leveleling criticim in any manner, but I hope that this incident serves as a loud wake-up call. Despite the best maintenance and operation, things like this are going to happen from time to time. The next time could be much worse.
