Cargill Glass Out. The Cargill grain elevators in Gilman, Illinois are served by a very distinctive switcher, CLCX 9698, Alco 2SM. Chattahoochee Locomotive Company rebuilt this Houston Belt and Terminal Railway #18 Alco S2 (8/1948) with a Caterpillar engine, improved lighting, and a number of other mechanical alterations, but the exterior would never be mistaken for anything other than and American Locomotive Works product. On the evening of Tuesday, February 2, 2021, sunset and snow complement the Cargill corporate colors as it sits awaiting the next day's work.
