In inclement weather, what is allowed during the inspection of passing trains?

In inclement weather, staying in the locomotive cab is allowed during the inspection of passing trains because it prioritizes safety for the crew. Harsh weather conditions can significantly limit visibility and increase risks associated with being outside the train. By remaining in the cab, crew members can maintain a secure position while still observing necessary safety protocols.

This approach also allows the crew to effectively communicate and coordinate with dispatchers or other personnel, maximizing safety without exposing them to adverse weather risks. The cab provides a controlled environment where the crew can monitor the train's functions and surroundings without being directly exposed to hazardous elements.
