Thank you, Mr. Chair.
Thank you to the witnesses.
For VIA Rail, the issue of positive train control was expressly referred to in the report on the Burlington collision. It sounds as though you're down the road a little bit towards positive train control, but you have a long way to go. CN and CP are implementing positive train control, but only in the United States. There is no regulation yet in Canada with regard to positive train control. Do you think there should be?
