What is a primary benefit of high-capacity dynamic brakes compared to their basic counterparts?

High-capacity dynamic brakes are designed to enhance the train's braking ability significantly compared to basic dynamic brakes. The primary benefit of these advanced systems lies in their capability to produce a much higher retarding force. This means they can bring trains to a stop more efficiently and effectively, especially when dealing with heavy loads or descending grades.

The increased retarding force is achieved through advanced designs and larger electrical components, which allow for better energy dissipation and control over the braking process. This improved performance not only enhances safety by reducing stopping distances but also provides more control during train handling, especially in challenging conditions.

While other options mention maintenance, fuel efficiency, or ease of operation, none directly relate to the core advantage of enhanced braking performance that high-capacity dynamic brakes provide, making the higher retarding force the most significant benefit.
