We are probably the third largest user of Canada's railways in terms of the tonnage we ship and the dollars we pay to the railways. So we're a huge customer. You have grain, coal, fertilizer, and forest products; those would be the four big users of the railways.
Our companies have developed close partnerships with the railways as part of their business, because in the fertilizer industry, you have to have that kind of partner relationship to keep your costs down and to deliver the product to the farmers.
And there are innovative things being done. For example, if you look at Canpotex, they've invested in a special railcar that is sized just to carry potash. It allows, I think, a 160-car unit train to expand to 210 cars. That's done to reduce the cost of transportation to get the product to Vancouver.
So our member companies are doing that. And yes, railway is the most important mode of transportation for us.
