A system for offloading a covered hopper railcar includes first and second auger-based conveyors. The first conveyor is adapted to fit partially under a covered hopper railcar's offloading gate when the covered hopper railcar is at rest on track rails such that a portion of the first conveyor is located to a side of the track rails. The first conveyor has a first opening in a top thereof adapted to be coupled to the offloading gate, and has a second opening in the portion thereof located to the side of the track rails. The second opening is in a bottom of the first conveyor. The second conveyor is coupled to the second opening of the first conveyor.
