If a locomotive has flat spots longer than 2 1/2 inches, what should be done?

When assessing a locomotive with flat spots longer than 2 1/2 inches, the appropriate response is to set it out at the first available point. Flat spots on wheels can lead to serious issues such as compromised braking efficiency, excessive vibration, and potential derailment. These abnormalities not only affect the performance and safety of the train but can also cause further damage to both the locomotive and the track.

Setting the locomotive out for repair ensures that it can be properly inspected and fixed without endangering the crew, passengers, or cargo. This action prevents the risk of accidents caused by mechanical failures and maintains the overall integrity of the rail system. Addressing the problem immediately by removing the locomotive from service allows for safer operational practices and upholds safety standards crucial for rail transport.
