I found this photograph from the early years of the former
Illinois Central Gulf Railroad at my Link page -
Fallen Flags.Org, which is located to the right of your
commuter screen at www.rr-fallenflags.org
The Illinois Central Gulf Railroad, was created on August 10th,
1972, with the merger of the Illinois Central and Gulf ,Mobile
& Ohio Railroads, creating a much larger system now controlled
by the former Illinois Central management.
One year in to the merger, these two former G,M & O engines,
were photographed still wearing their former company color
schemes and markings, but now working for the ICG.
