DESVARIEUX: So, Scott, let's take a look at the graph here. There were about 800,000 gallons of crude oil spilled in rail accidents between 1975 and 2012, and 1.15 million gallons spilled in 2013 alone. Why such a vast jump in the number of oil spills?
SMITH: Well, a couple simple reasons: a dramatic increase in volume from about 9,000 railcars in 2008 to 400,000 in 2013; and you've got an aging infrastructure for all this transport that's not adequately prepared to deal with the amount of traffic and the new explosive oils that are being pumped from beneath the surface of the earth.
