Big Chute Marine is the only marine railway of its kind in North America. This lock operates as a open carriage that runs on a railway going into the water allowing the boats to drive onto it and be lifted up by straps. The lift then proceeds to move across 60 feet of dry land to place the boat back into the water on the other side of the ridge between Severn River and Gloucester Pool. Big Chute has large grounds for picnicking and boater camping.
