What should be done during severe weather conditions regarding trailing movement through spring switches?

During severe weather conditions, it is crucial to prioritize safety and ensure that all equipment—including spring switches—functions properly. When facing such weather challenges, the best course of action is to avoid proceeding until the switch can be lined by hand. This allows for a careful inspection and assurance that the switch is in the correct position to safely guide the train. Given that severe weather can affect visibility, switch functionality, and overall track conditions, manually checking and lining the switch minimizes risks associated with unexpected switch positions during critical operations.

Taking proactive steps like this not only helps maintain safety for both the crew and the equipment but also prevents potential accidents that could arise from relying solely on automatic or improperly lined switches during adverse weather conditions. This cautious approach reflects standard safety protocols in the railroad industry during any scenario that could compromise operation integrity.
