Mr. MacDonald, I'll go to you.
I read your report from CN on intermodal transportation, which I thought was quite good. I note there was a really good piece in there on the GHG reductions that can be achieved with further rail transport, which I think was really great to see.
You also mentioned that funding innovation was going to be key in streamlining processes for infrastructure funding. Can you give us a little more detail on what innovations you're speaking of, other than automation, because I noted that? Is there anywhere else within the intermodal system that CN works with where there are opportunities for innovation?
