Well, there's very little oil that moves by rail. It's a very minuscule part of the market. A lot of it's heavy oil, which doesn't go well with pipelines, and generally it moves to refineries that are not pipeline-connected, so that's where it is. When the oil sands in Alberta were producing really well and it was over the pipeline capacity, that's when you saw some surges over the last five years in moving it by rail, but that has died down to almost nothing with the pipeline capacity expansions that have been done.
