I'm no expert, but some of the freight rails that run through Philly (including massive oil trains) are in visibly shitty condition (including one bridge in particular). Regulators freak out a lot more about passenger accidents, it seems, but I do worry about the impending
oil train bomb.
Several cars of a CSX train derailed Sunday morning in Northeast Washington. Three overturned and were leaking a hazardous substance, according to the D.C. Fire Department.
