I found this historic mid 1970's era photo from the former Chicago & NorthWestern Railroad at My Link page Fallen Flags.Org, located to the right of Your computer screen at www.rr-fallenflags.org

Railfan photographer Dennis Shmidt, photographed idling Chicago & NorthWestern EMD first generation model NW 2 yard switcher # 1011, at the C & N,W's huge Proviso Yard near west suburban Maywood Illinois on June 14th, 1975.
