What James said at the end is exactly what we're doing. We're hiring. We're acquiring locomotives. We've invested substantial amounts. In the last 10 years we've invested $20 billion in our railway. We've really accelerated our capacity builds in the last couple of years to make sure we can operate efficiently.
Crude by rail only represents about 3% of our revenues. It's a relatively small part of the business, and our focus is on moving the commodities that give us long-term stability in our revenue.
