I think it's all of the above. I think given what happened through the pandemic and then coming out of it, there was a sudden surge of traffic. There was a surge in demand, if you will, for traffic to move through all of the west coast ports.
The railways have a fixed number of railcars. They don't plan on a lot of surge capacity, and I would go back to the earlier point that I think this whole situation has really pointed to how fragile the whole supply chain is, the whole container supply chain.
Yes, you can point to the railways, because when you have so many containers piled up on the docks at the ports, it's really up to the railways to get those containers off the docks. The challenge that the container terminals had is that you can bring your ship up to the dock and try to unload it, but if there's no room on the dock to put down any more containers, they're stuck.
That's how they ended up backing up all of the vessels in Vancouver and where that frustration came from, but the same problem was occurring down in L.A. and Long Beach, to a far greater degree. At one point in time earlier this year, there were as many as 90 container vessels at anchor waiting to be unloaded.
