What do crewmembers check for before operating a hand switch?

Crewmembers check both directions for approaching trains before operating a hand switch to ensure safety. This step is critical in preventing accidents, as the presence of an oncoming train poses a significant risk when manipulating the switch. Checking for trains allows crewmembers to ascertain that the tracks are clear, thus ensuring that they can switch the tracks safely without endangering themselves or equipment.

While factors such as passengers on the platform and weather conditions are also important considerations in overall operational safety, they are not specific priorities directly related to the immediate task of operating a hand switch. The focus solely on checking for approaching trains aligns with industry standards for maintaining safety and preventing collisions in the rail environment.
