The problem is the majority of traffic from the Soo I don't think leaves via the eastern end of the line. How much of the traffic is actually interchanged with CN (Algoma Central) in the Soo. My understanding is there is not a lot of cross railroad traffic.

My understanding is this is almost two different railroads. The western end around the SSM area, and the eastern end from Espanola to Sudbury. I don't know how much cross the railroad traffic there really is. I wonder if it would make more sense to simply cut the service on the tracks from SSM to Espanola, have CN take over the west end, running the traffic that needs to go to CP to Franz, and having CP take the traffic from Franz to Sudbury.
