We did. We acted on it before October, and it's not just the train crew, but locomotives as well. Then on top of that, the lead time for track capacity can be upwards of 12 to 18 months. We did everything possible we could to inject the resources, actually starting back in the late summer or early fall. Again, we were able to withstand the volume that came at us, but then once winter hit, the resources that we brought in weren't nearly as productive as they would have been if we had had them in the summer.
For us, the key is to build track capacity and resiliency, as well as to have locomotives and people, and that's what we're doing.
