Sure. I'm happy to do that.
First of all, when private cars come into our network, they're coming in with our being aware of it in advance. They're not just showing up unexpectedly. We're working with our shippers as they bring on their fleet. Typically in CP's network, when they're bringing on private cars, it's because they have a specific commodity to move, and it's best to have it in unique equipment. It allows those shippers to manage their own pipelines with their own equipment.
We continue at CP to provide a common fleet for the movement of grain, so these new hopper cars that are coming into our fleet are there for the movement of all of our grain shippers who are moving from grain elevators.
The private cars, in our case, are used primarily for grain products, processed products like canola meal and processed oats.
