Busy times at Franklin Park Just east of Soo Line’s sprawling, former Milwaukee Road Bensenville Yard, an eastbound Soo Line freight meets a westbound Grand Trunk Western train at Franklin Park, Illinois, on February 9, 1992. On two of the tracks to the left, a pair of Soo Line EMD GP9s switch cuts of stacks and piggyback trailer flat cars for the railroad’s Bensenville Intermodal Terminal.
