A draft gear is a device which absorbs energy created by the forces associated in pulling, pushing, stopping, or coupling freight cars. The energy is dampened through a friction clutch, springs, and elastomers to prevent this energy from causing damage to the freight car structure or lading. There are generally two draft gears on each car which technically serve as reverse heat engines.
