When operating with solid double stack equipment, what is required regarding dynamic brake axles?

When operating with solid double stack equipment, fully utilizing the dynamic brake axles is critical for effective train handling and safety. Double stack containers are significantly heavier and taller than standard freight loads. The additional weight affects the train's braking dynamics, making the performance of the dynamic brakes vital in controlling the train, especially during descents or high-speed maneuvers.

Dynamic braking helps to reduce wear on the traditional air brake system and provides a more gradual braking force, which is particularly important with the increased center of gravity and potential for swaying that comes with double stack trains. By utilizing the dynamic brake axles to their full capacity, train crews can enhance train handling, improve stopping distances, and maintain better control, especially when operating on grades or in varying train conditions.

Limiting or modifying the dynamic brakes, or not using them at all, would compromise the train's ability to decelerate safely and efficiently, increasing the risk of derailments or other issues related to control. Thus, it is essential to fully employ dynamic braking when handling solid double stack configurations to ensure optimal performance and safety.
