CHSX SW1 #507 started out as Illinois Central SW1 #9022, built by EMD in June of 1946. It slid over to the Columbus & Greenville Rwy for a period of time before reaching the Cenex Harvest States Corp (now CHS Inc) as their #507. No photographer was listed for the photo which is now in my rr collection.
Scanned from a print I took. With Canadian freighter "SpruceGlen" in the background.
CHSX 507 is ex-Harvest States Co-op 507, exx-CAGY 507/607, exxx-IC 607, nee-IC 9022.
