We rely heavily on the experience of our locomotive engineers and on-train employees, who are well trained in identifying any areas of concern. They immediately report any incidents to the rail traffic controllers, who then in turn immediately contact police for intervention. They are of course very skilled individuals who operate over this territory for a living, and they know every turn and switch along the way. They are very good at immediately reporting any incident or behaviour that needs to be reported.
