Look, on our capacity side out there in the network, I still feel confident that there's many sections of our network where we can continue to absorb 20%, 30% business. In some sections that as we work close with Mark and his team, where we are reaching out to customers and understanding where that flow is going to come from, which will require a few more train starts. We have -- and, of course, I'm basing this off of us just over, let's say, three quarters ago when we were looking in the midst of a pandemic, and we were winding things down and record low numbers with respect to all of our assets. That's what we're basing this off of when we start talking about what we're going to need to pull out. So, yes, we're getting ready with locomotives, still going to be less than where we were a year ago or two years ago, with where the volume was at, we'll still see record levels with respect to productivity out of our locomotives and our people. So it comes down to the mix of business that we're going to see. We're making sure that we're able to provide that service that brings the customers to us. So that's something that we're really working on. And when we think about assets of people, attrition was a higher rate that we -- than we really expected throughout the pandemic. Those people, I think, it's just like the trucking industry, those who decided they may have thought they were going to hold on and not retire for a while. Well, they retired, and they packed it in, and it was a little too much for them. So, yes, we're going to see some of these assets come back. They're not going to be at the same levels that we had seen before. So, I think, as Kevin had mentioned, we're still going to see some good returns on all of this business that continues to come back in. And, I'm sorry, the second part, I think you mentioned was on the intermodal side. It was -- what was that question?
