I'll ask you the question I was going to ask Mr. Lavoie. Perhaps you have some experience as well as a consultant on these issues.
We've been told that the high-frequency rail is designed to compete with airlines between big cities. Between Quebec and Montreal, the cost per passenger—I just looked—is about, if you book in advance, $450 return. The cost on the slow-moving train is about $175 return.
In Europe, what price point are passengers willing to pay? What price premium are they willing to pay to go up from the slow train to the high-frequency, high-speed train? Is there a point of diminishing returns? If fares get too high, do passenger loads reduce?
What is the experience in...? I don't know if you have some examples of the level of subsidy that's provided per passenger in the markets you are familiar with.
