  1. When in the process of starting or stopping, and speed is below the effective range of the dynamic brakes
  2. Dynamic brakes can never be supplemented with the locomotive (independent) brakes
  3. When in the process of starting or stopping, and speed is above the effective range of the dynamic brakes
  4. Dynamic brakes can only be supplemented with the locomotive (independent) brakes when operating light power (no cars)

Answer: When in the process of starting or stopping, and speed is below the effective range of the dynamic brakes
Feedback:
Use dynamic brakes to their fullest extent. Extended-range dynamic brakes normally start to lose their effectiveness at speeds of 5 mph and less. This is an example of when to supplement the dynamic brake with the independent brake.
