A method of retarding the locomotive and train by using the locomotive traction motors as generators. The current generated by the motors is dissipated through fan-cooled grids.
Method of braking an electric motor, with the motor used as a generator and the electrical energy generated being dissipated in resistors.
A method of train braking where the kinetic energy from the train movement generates current at the locomotive traction motors, and is dissipated in a resistor grid on the locomotive.
