If I remember correctly NS is the one major railroad that never centralized its dispatching. Is this correct and if so where are all the dispatching centers located. It looks like there is one in Harrisburg, PA but where else. Thanks!!
NS has them in the division headquarter's city for each division.
Roanoke, VA, Greenville, SC, Atlanta, Knoxville (not sure if this one is still in action, but I think so), Harrisburg, Bluefield WV and one in Pittsburgh.
I am less certain on the other midwest DS offices. One should be in Detroit.
I hope others can fill in the rest.
One question I have is how may desks are in Harrisburg and what are the limits of their territory?
