If Snowpiercer encounters extreme obstacles or heavy snow, the Engine can deploy a retractable Plow<ref>[[Justice Never Boarded|S01E05 - Justice Never Boarded]]</ref>. Both the Eternal Engine and Big Alice have this capability. When closed, the plow seamlessly retracts into the Engine's hull and does not disturb its aerodynamic design. While deployed, the pilot can change the configuration of the plow to best serve the rough terrain ahead. On top of the Engine is a large spotlight directly above the cockpit. There is also a Wilford Industries logo on the front of the Engine. There is also a [[Weather balloon]] deployment system, called sound balloons, installed in the roof, beneath retractable panels and a forward and aft flare system. There are a series of hydrogen port intakes, on the upper sides, toward the rear of the Engine.
