Here's an elevator on my layout with a similar idea to using the Walthers corn silos.
Although the materials (metal vs concrete) differ, the arrangement is essentially the same. There's a pair of bins and an elevator leg. I kitbashed the truck unloading shed using leftover parts from a Walthers ADM elevator kit and there's a grate for the truck dump inside it from a Walthers Glacier Gravel. From the distribution head, there's another pipe (the supports for which are visible above) to load hoppers.

The kit includes both a vertical elevator leg and a horizontal conveyor section. The horizontal piece can be omitted if you're not using other parts of the Walthers ethanol complex. If using the "corn" silo kit for a stand-alone elevator, you'll need to add a way to get incoming grain to the "leg" (using an unloading shed with a dump pit and auger for instance), and more modifications to load railcars or trucks. It's typical enough of many elevators it can easily be made to look right. You can also link to other types of bins to add capacity, as with any elevator.

The conveyor part is sort of needed - How do you fill the silo without it? They are much too large to fill with a portable conveyor....

Has anyone used walthers' ethanol series' corn silos & elevator kit as a stand alone grain elevator without the horizontal grain conveyor part?
