Exterior, three-quarters “roster” view of three Soo Line EMD diesel locomotives at Bensenville, Illinois on May 19, 1990. The two SD60M locomotives, #6058 and #6059, display the railroad’s final color scheme of cherry red with white lettering. In the middle is SD60 #6006, still in the road’s previous white and red color scheme with black lettering. The “M” designation on the newer locomotives indicated their wide, “comfort cabs,” first used by Canadian National. Wide cabs have since become standard on new road freight locomotives in North America.
