The Dynamic or Rheostatic brake is applied by the crew to control the train without any application of train brakes or locomotive brakes. Important guide lines for using the dynamic brake of locomotive are given below.

For applying dynamic brake, the master controller (MP) is brought to the 'O' position from the traction mode. Then the MP is turned towards the braking position. Before taking the notch for applying dynamic braking the following should be carried out for smooth braking in the train.

  1. Before using dynamic brakes load should be bunched up on the buffers by applying A 9 slightly and then releasing.
  2. The current limit should not go beyond 750A per traction motor.
  3. While applying dynamic brakes, the locomotive brake should be released. The locomotive brake should not be applied while applying dynamic brakes as it may cause wheels to lock and slide on the rails.
  4. The high-tension compartment should be closely observed for any signs of overheating.
