Thanks to all the witnesses for being here today. We apologize for being late from votes, but that's what we have to deal with.
I'll start with you, Mr. Bradley. You've given us some really interesting numbers. In terms of dangerous goods, you spoke about two million shipments, but as you mentioned, it's really hard for you to know.
We've seen rail going from 500 carloads in 2009 to probably 510,000 carloads in 2016. What have you seen in the industry? Is there an increase in terms of shipment of dangerous goods in the past five years, let's say? Do you project that there will be an even bigger increase, or has it been stable for a while?
