Dynamic Brake
Appearance
To prevent wear and overheating of the brake shoes , most locomotives and railcars feature alternative ways of slowing down, such as rheostatic , hydrodynamic and engine brakes . These brakes use the powertrain of the vehicle as a means to slow down, instead of relying on the brake shoe friction.
Dynamic brakes are further described in the Powertrain section of the manual for each powertrain type.
