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.
