What should be done when setting out a car with a hot bearing?

• A. Use snow to cool the bearing
• B. Cut out the air brakes
• C. Inspect equipment after moving it
• D. Move faster than 4 MPH

Answer: (B)

The appropriate action when dealing with a car that has a hot bearing is to cut out the air brakes on that specific car. This is critical because a hot bearing poses a risk of fire or failure, and maintaining control of the car's brakes is essential to prevent any additional hazards during movement. By cutting out the air brakes, the crew can mitigate the risk of brake failure or overheating due to the hot bearing. It's important to understand that using snow to cool the bearing is not practical or effective in a real-world scenario. Simply inspecting the equipment after moving it could also lead to further complications, as it would not address the immediate danger posed by the hot bearing. Lastly, moving faster than 4 MPH is dangerous and contrary to safety protocols related to handling problematic cars, as excessive speed could exacerbate the situation or lead to a loss of control. Therefore, cutting out the air brakes is the safest and most appropriate action to take in this situation.
