First off no question is stupid if you don’t know the answer. Ignorance would be not asking question.
Food products, auto parts, packaged goods, lumber, paper products, tires, beer, wine, soft drinks, water, etc.
I currently have an auto assembly plant, which serves 86’ boxcars and other shorter hicube boxcars. Products could be tires, fenders, frames, seats, motors, etc.
I have a gypsum manufacturing plant, which makes packaged gypsum cement products and wall board (drywall). This wallboard goes into double door or all door boxcars. The Chili and Produce plant that I have handles insulated cars, reefers, and boxcars for the can goods and fresh produce. I also have a Pepsi plant that has boxcars for finished product outbound and ingredients and packaging inbound-paper products, pallets, plastic bottles, Al. cans, etc.
My other industrial areas consist of a feed mill which handles boxed products, a beer dist., mixed foods, frozen foods and even a refinery and steel fabricator that handles inbound loaded boxcars for supplies and parts needed to maintain the facilities.
I used to work for a railroad in Chicago as a Special Agent (Railroad Police) and my job was to inspect every load that came in. I have seen just about everything carried in a boxcar. I have seen boxed cereal in 86’ boxcars. The railroad carries just about anything.
You can check out some information on OPSIG list or any waybill car forwarding software programs. They have many commodities listed with what types of cars that they would be most likely used for that particular item. The program that I use is from Shenandoah Software. They have a sample program on the Internet that will show you some of the commodities and which cars the products that would most likely be loaded into.
Hope this helps some.
