Switch Couplers are responsible for connecting and disconnecting railcars in a train yard or industrial setting. They ensure the safe and efficient operation of rail systems by handling couplings, inspecting equipment, and coordinating with other rail workers. Junior roles focus on learning the basics of coupling and safety procedures, while senior and lead roles involve overseeing operations, training new workers, and ensuring compliance with safety standards.
