Which action is considered best practice when using dynamic brakes on locomotives in high-demand situations?

Gradually applying dynamic brakes and monitoring the response is recommended as best practice in high-demand situations because it allows for a controlled and measured reduction in speed. This approach helps prevent potential wheel slip or locking, which could lead to loss of traction and control of the train. By monitoring the train’s response as the dynamic brakes are applied, the engineer can make necessary adjustments, ensuring stability and safety, especially in varying track conditions or when navigating steep grades.

Using the highest power setting indiscriminately may overwhelm the braking system, leading to potential failures or harsh braking actions that could destabilize the train. Likewise, activating all brakes at full force can also result in abrupt stops, risking derailment or damage to the train. Relying solely on air brakes could limit control and response time when dynamic brakes are more effective in such scenarios. Thus, a gradual and attentive approach to applying dynamic brakes is crucial for optimal train handling and safety in high-demand situations.
