What is the main reason for not operating a train for an extended period in the switching position?

The main reason for not operating a train for an extended period in the switching position primarily centers around the potential for damage to car equipment. When a train remains in the switching position for too long, it may subject the train's mechanical components and car equipment to undue stress or wear. This could lead to operational problems, increased maintenance costs, or even safety hazards if vital systems are compromised.

Maintaining the integrity of the equipment is crucial for the safety and reliability of train operations. Each component of a train is designed to operate within specific parameters, and prolonged exposure to conditions outside of these parameters—such as improper alignment in switching—can adversely affect performance.

While other options may seem relevant, they do not focus on the immediate physical and mechanical concerns related to train operation in the switching position. For instance, improving station service delays, enhancing passenger comfort, and ensuring safety protocols are all important considerations, but they do not address the direct risk of equipment damage that can occur from prolonged service inappropriately aligned.
