I'll do my best.
Let me start with the actual location of the facilities. The customers by and large determine the location of the facilities. We don't own the facilities where these transload operations are occurring.
To the second point, from a risk mitigation standpoint, that's something we've been very seized with as this crude by rail has grown. What we've done specifically at CP, and what we continue to do, is through an investment where we're taking jointed track out and we're replacing it with ribbon rail, or continuous welded rail, heavier rail, stronger rail, more ties, more ballast. We're in about a five-year process now where a lot of these territories, from a risk assessment standpoint or from a risk mitigation standpoint, that this crude runs on is where we're strategically investing additional money. Through inspection, we've purchased during the process.... Just last year we ordered three rail defect test cars that we'll own ourselves and will operate on a continuous loop in these areas where the crude moves. If there is a track defect, a rail defect, we'll find it and mitigate it and remove it before it causes a derailment.
There are multiple layers of approach that we're taking to mitigate the risk and to reduce the likelihood that an incident will occur in these areas.
