We haven't assessed the report in those kinds of critical terms. As far as we know, the information that they used from TSB data sources was accurate. We have no reason to question that. I think the question of rail versus pipeline safety when it comes to transporting dangerous goods is a lot more complex and challenging to answer than may appear on the surface.
It really requires an apples-to-apples comparison. You have to aggregate volume data from various sources. You need a common denominator to compare them on an apples-to-apples basis. That's very difficult.
From our perspective, the risks in pipelines are very different. They relate to, for example, fracturing or fatigue cracks in the pipeline, to interactions with the environment and sometimes to third party intervention, versus rail, where you have hundreds of tonnes of train operating on steel rails in a variety of climatic conditions.
The risks are very different. At the end of the day, our job is to identify where there are deficiencies and where more needs to be done. We don't make those kinds of comparisons as to which mode is safer than the other. We believe that, whatever mode is used, it needs to be done as safely as can be.
