From the ocean standpoint, there are 40s and 20s. It's a function, a multiple. When we look at providing railcars to off-load from the ports, we provide about 30 kilometres' worth of railcars every single day to the ports to bring in containers and also to bring empties or loads back. Ideally, you want as much as possible for those to be 40s and 20s, because they go directly to the ships.
Now, on our inland terminals, we use 53-foot containers, which is the North American standard. We try to keep those out of the ports in order to maximize exactly how many 53s you can put on for the inland versus the 20s and 40s out of the ports. We have a whole group trying to match that up every single day.
