Looking at the ground in front of the loading door of the Grain Elevator you will see a metal plate. This covers a hopper, originally under the railroad siding, through which grain was fed into the elevator.
A farmer would shovel the grain from his wagon into the hopper. It was also possible to unload grain from railroad boxcars spotted on the siding into the hopper. A screw augur carried the grain from the hopper to the bottom of the switching tower of the elevator. Here the grain was picked up by a bucket elevator which carried it to the top of the tower where it was routed into one of the grain bins.
