When handling locomotives with flat spots, what must be done?

When locomotives develop flat spots on their wheels, it indicates that the wheels have become uneven due to excessive braking or skidding, which can lead to a rough ride, increased wear on the locomotive, and potential damage to the track. Therefore, the appropriate action is to set out the locomotive at the next applicable point after reporting the issue. This approach ensures that the defective locomotive can be inspected, repaired, or serviced without risking further operational issues or safety hazards.

By setting out the locomotive, you can prevent potential accidents caused by the deterioration of the wheel condition, leading to a smoother operation for the remaining trains on the track. It also allows maintenance teams to address the issue properly, which is critical for the ongoing safety and efficiency of rail operations. This procedure falls in line with the responsibility to maintain high safety standards in rail transport.
