It goes back and forth a little bit. Fuel is either our number one or number two cost driver for the railroad. I know that for CN, our fuel expense on an annual basis is well over $1 billion. It is a huge expense for the railroad. It's why we spend a lot of time and a lot of effort looking at fuel conservation and alternate fuels. There's a significant potential advantage for us in that as well, because fuel is one of the biggest cost drivers for the railroad.
