Can I just jump in? I'm glad that you asked about the 2013-14 crop because it predates this committee, and there was a lot of information shared during that time that's probably worth repeating.
First of all, this was the largest grain crop in the history of the country. It was 20 million metric tonnes larger than the average crop. It takes 100 extra trains—I forget the exact metrics, but in fact, it's hundreds of extra trains—to move that additional crop to an export position. At the same time, we had the worst winter in 100 years, or certainly in 75 years. Those of you who are from Winnipeg will recall that in June the municipal water pipes were still frozen from that winter. Unfortunately, with existing technology, there's an impact on rail. From a rail safety standpoint, we need to shorten trains. In addition, there is broken rail. There are broken wheels. These are facts of physics that we prepare for, but which still affect railways.
We had this perfect storm, and what have the railways done in response since then? They have massively invested in their network. You can't expect them to have hundreds of railcars, crews, and locomotives sitting on standby for that once in a hundred years crop, but they have invested, and it's exactly the kinds of regulatory provisions like extended interswitching that can prevent additional investment. We have to ask ourselves, what is the formula for this success in having successful, efficient railways in this country that are globally recognized as being among the most efficient? The key there is investment.
