There would seem to have been—and certainly this is what we have seen and heard about—an increase in the shipment of oil by rail simply because everybody's waiting for pipelines to be built, not least those who are on this side of the House.
The longer trains, heavier trains.... I'm not sure if the new cars in fact have more capacity per car than do some of the ones that have been taken out of service, but there does seem to be a perfect storm developing. When you add abnormally cold conditions that can spike, particularly at certain times of the year, it would seem that we're dealing with an elevated risk. I'm wondering if, in terms of the service characteristics, the way trains are put together, the length, etc., you're convinced that the railways are making those adjustments appropriately.
