That's true to some extent, but a lot of it is based on the contracting arrangement and on what certain other countries are doing.
When a railway says things like that, what they would like to see is for grain movement each week to be even all the way through, but the reality is that customers should dictate. In pretty much any other sector, you're dictating to your service supplier what you need each week and what you want to see. When you have a railway, they want to maximize their assets and sweat them week to week to week. They want a nice even grain flow, and that's just not the way the grain sector works.
