Thank you for the question, Mr. Chair.
Canada is a great country, but we also have some of the harshest climates anywhere in the world, as far as operating trains at higher speed is concerned or even at the speeds we are going today.
There are a lot of examples of high-speed, high-frequency trains around the world, but I would say that I don't know of one that operates where there is a temperature differential in the range of about 70°C from winter to summer, and sometimes, in some seasons, very drastic changes in the same day. I cannot give you any examples of something like that. There are trains that operate in colder climates than the south here, the corridor—I'm thinking of Siberia—but they are not high-speed trains.
