How should angle cocks be maintained during train operations?

Maintaining angle cocks properly is crucial for safe train operations. Angle cocks, which control the flow of air in the train's air brake system, must be fully closed or fully open to function correctly and prevent any potential issues. Leaving them partially open or partially closed can lead to air leaks, which might result in inadequate braking performance or a complete brake failure. Proper maintenance ensures that the air brake system operates efficiently, providing safe stopping capabilities and reliable performance during train operations. Adhering to this standard practice minimizes the risk of accidents and enhances overall safety on the railways.
