Retractable couplers are designed to improve the safety and efficiency of train operations, particularly during the processes of loading and unloading. These couplers can be drawn back or extended, which allows for a more controlled approach when connecting and disconnecting train cars. This feature significantly reduces the risk of accidents, such as sudden jerking that may occur with traditional, rigid couplers.

By employing retractable couplers, train systems can ensure that there's a safer distance maintained between the cars when they are being loaded or unloaded, minimizing the chances of injuries or damage. This enhances overall safety measures in both passenger and freight operations.

In contrast, the other options such as automatic signaling systems, modular train designs, and passenger tracking technologies serve different operational purposes and do not specifically relate to the use of retractable couplers. Automatic signaling systems focus on train movement coordination, modular train designs refer to the flexibility and adaptability of train configurations, and passenger tracking involves monitoring passenger flow and behavior, none of which directly enhance safety during the physical connection and disconnection of train cars.
