If you belong to a club, what industry do you model on the layout? If you have your own personal layout, what is your major industry? For example, my Club industry is a scrap yard with outbound rail service...tTruck brings it in, the load is cubed, and shipped out in gondolas to Shire Oaks, where it is classified into a train of similar material, to be shipped to the steel mill, and other places. My eventual layout main industry will be a coal tipple, and a power plant.
