Unmistakably Alco
Number 332, working for the Indiana Hi-Rail Corporation, is an Alco C420. Discerning the lineage of this locomotive was fun: to begin with, the gray color made me think of the Louisville & Nashville.
Indeed the engine ran for for the L&N as number 1332. [It seems that IHRC simply removed the "1" to create a new number: 332.] But the story goes on: the bell on the nose is a tip-off that this locomotive once ran for the Monon, which was subsumed into the L&N in 1971. The C420 was purchased new for the Hoosier Line in August of 1967 and ran with the number of 515.
The image was made near Charleston, Illinois, on one of the several lines owned by the Indiana Hi-Rail Corporation. I believe this particular one was once the Nickel Plate. One image by Richard Koenig; taken on a humid day in August of 1990.
