Steve great question. Let me say this, and I'm going to have two gentlemen that are driving an easiness of per day, both Mark. Mark part of the storage, John of part of the store and their teams. That's the beauty of this. It's not singular. It's diversified. What Mark has done in Canada relative to driving well down train speed up or 100 series trains and never run better. The focus there and the intensity and the opportunity to drive not only train speed, but asset turns of locomotive velocity and fuel efficiency. Mark and his team are doing a phenomenal job. And at the same time, part of the task force, we've taken a challenge, which comes with growth. We turned it into an opportunity. And John took his team and has turned into an organization that's focused on process, focused on PSR principles, where we turn assets, where we get better for our customer, we whiteboard of the GM, we whiteboard with the Lantus, we whiteboard with our customers so that we can identify what's possible of the we work to strive to achieve the art of the possible. I mean it's all about asset turn, speed and velocity. And as a result of that, too, although I said I'm going to let these guys talk, I get a little card of way here. Part of what we learned that we're super excited about is with a little bit of strategic investment much like in the play book of PSR in the past. This isn't about cutting costs. It's about strategically and surgically investing money to create capacity and resiliency to eliminate bottlenecks, turn assets more. It's about locomotive productivity. It's about train speed. It's about crew productivity. It's about fewer recrews. It's about turning assets, creating cars of capacity through doing that for our customers so that we can create more loads with less cars. It's PSR 2.0 and John has done a masterful job of integrating and starting that evolution in Mexico since that task force was created. So again, a couple of highlights, John, a couple of highlights, Mark you guys have done it. I get -- I'm the proud guy that gets to talk about it. I love it when I see it happen, but let me give these guys a chance to share a couple of highlights for you, Steve as well as the rest of our investors to give you some meat on the bones so to speak, not just a bunch of rhetoric, but real live examples of the of the possible.
