Who's railroad is this? 4 NS units on a UP manifest race a CN detour led by a IC SD70 northbound on UP's Chester Sub, near Fults, IL. The CN detour was due to heavy flooding north of Memphis on CN's line between Memphis,TN and Fulton,KY. CN would run a total of 3 detours today, all intermodal. However the CN detour here had a large cut of priority manifest traffic on the head end. 5/5/10
