In many countries, okay? The other thing is that they don't work in silos. They are what they call the "first line of defence" in safety and security related to the railway system, but they're not the only police force that can investigate matters, right? The RCMP and other police forces can and do investigate, depending on where they have jurisdiction.
For example, if something happens on a rail line on the island of Montreal, probably, the Montreal police will investigate. If it's between Montreal and Quebec City, then it will probably be the Sûreté du Québec, depending on where they have jurisdiction. They collaborate. Especially for complex investigations, they collaborate together.
