DYNAMIC BRAKE
Purpose of Dynamic Brake
The dynamic brake is used as retarding brake to control the speed of a train. It is not intended that the dynamic brake alone will always limit the train to the desired speed and, at times, the automatic train brakes may have to be applied in conjunction with the dynamic brake to control the train at the desired speed.
Principal of the Dynamic Brake
The dynamic brake, although similar in effect to an independent air brake application, is fully electrical and does not produce friction between the brake shoes and wheels, thereby avoiding heat and wear on these components.
