Let me start by saying that the Prince Rupert grain terminal is separate from Ridley. Ridley is the coal and coke terminal.
I don't know how to answer your question. Every participant in the supply chain needs to have resiliency. As we've spoken about, whether it's more track, more people, more cars or more locomotives, we know there will never be a perfect linear movement of grain. You need to be able to catch up.
For the terminals in Vancouver, it's somewhat the same. If there's heavy rain and they can't load the grain into the ships because we can't use tarps or holes, then that stops the entire system. What we work with them on is to first of all make sure we have the proper understanding of what they're going to unload, how they're going to unload it and what grain they need from us so that we can get it there and maximize that part of it. The resiliency we need in a place like Vancouver is to be able to unload 24 hours, seven days a week, in the rain, just like we need to be able to run when it's 30 below zero and snowing dramatically. In terms of rain, Joan can speak to the issues of going through the spiral tunnels.
Those are all very tough things we need to have resiliency on, and that will definitely help the supply chain.
