When operating through turnouts or disturbed track areas with the air brakes released:

  1. Do not exceed dynamic brake 4 until the entire train has passed the restricted area.
  2. Do not exceed dynamic brake 4 until at least half the train has passed the restricted area.
  3. Do not use any dynamic braking. Dynamic brakes can't be used when operating through disturbed track areas or through turnouts.
  4. Any amount of dynamic braking (DB 1 through DB 8) can be used.

Answer: Do not exceed dynamic brake 4 until at least half the train has passed the restricted area.
Feedback:
By not exceeding dynamic brake position 4 until at least half the train has passed the restricted area, we limit the amount of tractive effort pushed onto the rails. This helps to prevent track damage and derailments caused by excessive dynamic braking. Exception: Trains utilizing GE Trip Optimizer are exempt from the above requirement to use dynamic brake handle position 4 when in Auto Control only.
