I ask that because I was in CN's Chicago centre a year ago, and they were showing me on their computer system how they could tell where a car was and what was in that car at any given time. Are they providing you information on how many grain cars are sitting empty in the sidings, or can you get it?
Je pose cette question, car je suis allé au centre de Chicago du CN il y a un an, et les représentants me montraient comment ils pouvaient voir, à l'aide de leur système informatique, où se trouvait un wagon et ce qu'il transportait à tout moment.
