No. I'll tell you what operations mean. You didn't ask me the question. I'm the railway expert.
Operational requirements does not refer to finances. Operational requirements means what a railway needs to do to conduct its operations.
A railway must hook cars onto a locomotive. That involves switching from one train to another. That causes shunting noises, which we heard a lot about. A railway must move those cars along the track. You heard that there are very long trains, often now two to three kilometres in length. That's part of railway operations.
A railway does what is called “humping” in the industry. That happens at a yard, and it's when the cars are sorted onto the actual trains. Those cars are taken down a hill and the cars are sorted onto the proper trains. That's rail operations.
Railway operations also means inspecting the train before the train leaves. Often before the train leaves or when the train consist is being made, the locomotive is operating and it's idling. So there's a potential idling noise, a potential vibration noise. But once that train is set up, the railways are obligated, by law, by federal railway safety law, to inspect that whole train before that train leaves the yard. That, too, is part of railway operations.
To categorize it very broadly, anything that involves the movement of a train from the point of origin, where it collects its goods, to the point of destination, where it delivers the goods, are all operational requirements. It has nothing to do with the financial bottom line. Yes, that's how they earn their income, but the financial requirements are separate. I think we saw when we were talking about the airlines, when we were talking about reporting, that the two are different. This is what a railway has to do to carry out its business. All those activities we heard about, yes, they're part of railway operations, and that is why that is in here. They must try to limit the noise or the unreasonable noise. I think we've agreed now to limit it to the minimum. But all those are operational requirements. They can't function without doing those activities.
