Similarly the additional risk of being injured because of the increase in rail traffic from oil cars alone is also so small it would be near impossible to measure.
Well, I used to say that, after 47 people in Lake Megantic got burned alive in their homes, that argument has become a bit more difficult to make. Sure, this could have been a products or ethanol train, but to argue that shipping more crude on the rails has no safety implications misses the mark.
Trains derail ever so often, just 5 years ago an entire train of empty lumber cars got blown off a trestle only a couple of miles west of Casselton. Coal and wheat hoppers end up in the weeds multipe times every year. In 2002 a derailment involving Anhydrous Ammonia tankers killed one and injured 332 in Minot. Still safer than trucking the stuff, but moving 10,000tons of hazmat at a time through the center of cities does bear some risk.
