I couldn't tell you. We're told that the track is tortuous, that the convoys are longer and that it would then be difficult to increase speed. In another case, we're given other reasons. Honestly, I don't know why the speed is reduced in Drummondville. On the Beloeil to Montreal section speed is reduced and we are monitoring the situation. I think that municipal police monitor it to ensure that CN is not in the wrong. Between Charny and Saint-Apollinaire, there is the Chaudière River. CN probably decided to reduce the speed because of the geography there. CN has had to face many catastrophes, and perhaps it decided to reduce the speed wherever it's most difficult.
