What is the purpose of operating traction motor blowers for 10 minutes when encountering water above the rail?

Operating traction motor blowers for 10 minutes when encountering water above the rail is critical for the maintenance and safety of the locomotive's traction motors. The primary purpose of this action is to dry out the motors to prevent damage. When water comes into contact with electrical components, such as traction motors, it can create short circuits, leading to electrical failures and substantial damage. By activating the blowers, air is forced through the motors, helping to evaporate moisture and ensuring that the motors remain operational and safe to use.

This procedure helps maintain the integrity and longevity of the traction motors, allowing the locomotive to continue functioning effectively and reducing the risk of costly repairs or replacements. Additionally, it plays a vital role in ensuring safety by preventing potential electrical hazards that could arise from wet components.
