While I must wonder if these newer DOT-117 cars could have avoided Megantic, I trust that the seven Class I's are not operating in as reckless a manner as was the MMA-Q. I realize that a "sales pitch" of "let me show you the wreck we just had" is not the greatest, but if in fact the new cars saved the day (and not simply because a TV News reporter and a Chessie "spinfraumeister" say so), railroad Marketing should be shouting that from the rooftops - well, at least to the shippers and legislators.
