I think you've given a good answer.
The second topic I would like you to talk about is fatigue. One of my friends in Saguenay—Lac-Saint-Jean is the only survivor of a head-on collision of two trains. The collision happened in the middle of the night, at 3:00 or 4:00 in the morning. My friend, who was in the locomotive pulling two trains of goods, said to his crew mate that he thought another train was coming because he had just seen the light through the trees. He was right. He was thrown from the car, but his companion died, as did the two crew members in the other locomotive. He was the only survivor.
You are talking about fatigue, and you are suggesting an amendment that we will study seriously. Is the time spent waiting before work calculated? From speaking with airline pilots and cabin crew, we know that there is time spent waiting before starting work. It's not like someone shows up at work at 8:02 in the morning and the train leaves at 8:03. That's not how it works. I have never driven a train, nor have you, since you're a lobbyist, but how does that work?
