On your first point regarding U.S. competition, it's important to note that interswitching or competitive line rates or any pro-competitive measure only works if you have the two railways willing to compete for each other's business. CN and CP haven't always shown a willingness to compete for each other's captive shippers. The only time it's effective is when a third party come in. That point is very important.
In the U.S., the shippers look at our interswitching, and they want it as well. They call it “competitive switching”. In July, the Surface Transportation Board announced that they were going to do a regulatory study on improving their current provisions on that. Through the fall, they're having hearings with shippers and others in the rail community there to establish the same thing.
