Abstract
A device and system for controlling travel of a railcar along a set of rails is provided. In one example, a railcar stop is coupled to the set of rails and is selectively movable between a first position wherein the railcar is free to travel along the set of rails and a second position wherein the railcar stop engages the treads of the wheels to thereby prevent travel of the railcar in at least one direction along the rails.
