Dynamic brake is a braking system type designed to aid mechanical brakes when slowing down trains .

It is featured by some locomotives and railcars , made possible by their specific powertrains . Because dynamic brakes don't rely on train brakes , they help reduce wear and friction on the brake shoes .

Depending on the powertrain type, there are different types of dynamic brakes, such as rheostatic , hydrodynamic and engine brakes.
