What speed must a train reduce to if flat spots on a wheel are discovered?

• A. 20 MPH
• B. 15 MPH
• C. 10 MPH
• D. 5 MPH

Answer: (C)

When flat spots are found on a wheel, it indicates a potential issue that could affect the train's handling and safety. Reducing speed is critical to minimize further damage and ensure the safety of the operation. The specified speed limit of 10 MPH for trains with flat spots is designed to allow the train to operate safely while mitigating risks associated with the flat spots, such as increased vibration and the potential for loss of control. Maintaining this reduced speed allows the crew to manage the situation more effectively and makes it easier to bring the train to a stop if needed. Compliance with this speed limit is crucial for ensuring not only the safe operation of the train but also the safety of passengers, crew, and infrastructure. In this context, the other speeds listed are either too high to mitigate the risks associated with flat spots. It is important to emphasize the need for adherence to these guidelines in operating rules to maintain safety and prevent further incidents.
