I live 5 minutes from where this happened.. Non-issue.. Most all of it evaporated already..
What that article doesn't tell though is that the same bridge collapsed 3 years ago. It's an old as heck swing bridge that should have been replaced ages ago. For those wondering this is a Conrail shared assets line on the Penns grove Secondary. This line is 99% of the time trains pulled by CSX. Very rarely do you see a random NS on it.
