Usually through contact with our employees, or I suppose they would call 911. All the police forces can get a hold of us very quickly. The network works extremely well. We rely heavily on our infrastructure owners as well, who do an extremely good job of having track forces out there and signaling any incidents to us. Our primary contact is our employees, our operations control centre, or simply by calling the local police.
