Do the dynamic brake axles need to be limited on a consist of 4 SD-60 locomotives with high capacity dynamics?

The dynamic brake axles need to be limited on a consist of 4 SD-60 locomotives with high capacity dynamics due to the potential for excessive braking force generated by multiple locomotives when relying on dynamic braking. When several locomotives equipped with high-capacity dynamics are used together, the cumulative effect can lead to an imbalance. This may cause issues such as wheel slip or flat spotting, which can damage the locomotive's wheels and affect overall train handling.

By limiting the dynamic brake axles, the braking force is distributed more evenly across the train and helps to prevent such complications. Understanding the dynamics of multiple locomotives working together is essential for safe train operation, particularly in scenarios involving heavy loads or challenging track conditions. This practice ensures that braking forces do not exceed safe operating limits, protecting the integrity of both the locomotive and the entire train system.
