DMU is where several of the rail systems are going, but they're not able to purchase Canadian-made.
Mr. Fuller and Mr. Binns, there are two essential things that have to happen. One is PTC, which you didn't spell out, but it's positive train control. This means that it's not reliant on somebody seeing a light through the fog before they stop a train. It's actually electronics that are transmitted to the train to say, hey, slow down. Perhaps this would have stopped the tragic accident in the Niagara region last spring. But positive train control plus some form of temporal separation...and temporal separation requirements require the cooperation of the freight railways. We don't have a whole lot of cooperation from the freight railways. I don't know if you've heard about what's going on in Montreal. Montreal wants to electrify their rail lines and the freight railroads are saying, “No, we're not going to let you. We don't like electric wires over our trains.”
Could you comment about those two aspects, Mr. Fuller and Mr. Binns? What is it that we should be aggressively doing to move us in those directions?
