Sure, I can handle that.
It is something we do assess. We're looking at both the passenger and the freight rail systems and how they work together. As you mentioned, there are issues sometimes, given that the demand for both is increasing. It is something we assess as projects come in—on passenger rail, for example—in terms of how the balance between those two works out. It is something we have to assess as we go forward on any commuter rail projects, in working with our partners.
