We constantly review safety and security measures by other railways, whether it be Amtrak or Europe or Australia, to see what their best practices are. Based on our risk assessments, we determine what actions we should take.
If I may, I'm going to go back to your passenger list question, just for a clarification. Every person who gets on our trains has their ticket scanned so we know exactly how many people and what people are aboard our trains. This is consistent with the safety and security plans we submit to Transport Canada. We know who is on our trains based on ticket scanning, and we've implemented that technology.
