One is that the number one cause of train derailments is track infrastructure failure. We do more track infrastructure inspection with technology than is required by regulation. That's one of the reasons why we're leading the industry.
The other one is investment in technology. We have technology in place right now—and you heard about requests for exemptions from rules—for coal trains we operate in British Columbia, where the brake tests on those trains are done using technology that's far superior to the manual processes that have been in place for years. It costs us money to do that.
