A railcar door opener includes an alignment sensor for aligning the opening tool with a railcar door latch and a railcar door latch opener for releasing the railcar door latch. A railcar door closer includes at least two closer arms configured to close railcar doors on or near the bottom of a railcar. The opening and closing tools are each coupled to the tool carriage, and the tool carriage is moveably attached to the support. A controller controls movement and operation of the tool carriage, opening tool and closing tool.
