I think it's about the speed at which you can move cargo. If we think about the ISO boxes, then we want to accelerate the movements of these cargo boxes. That is the key to it all. That goes through how you make them flow on the network, whether it's by roads, by ship—short-sea shipping—or by rail, how you move them across the borders, and how you make sure that all the necessary security measures in modern transportation are done? It's really the acceleration of the movement of goods that's important. That's the concept that surrounds landing a Triple E vessel in a big port, unloading it as fast as possible, distributing that cargo across the network and integrating that network with all the different areas. Those are key.
I will also add that you have chances to make it a bit automated and certainly to have low carbon emissions, if you plan properly.
