What is indicated by very low Straight Air pipe pressure?

Very low Straight Air pipe pressure is an indicator of potential leakage issues within the air brake system. When the pressure is significantly lower than the normal operating range, it suggests that there may be a leak somewhere in the system. This situation affects the ability of the brake system to function properly, as adequate pressure is required to engage the brakes effectively. Recognizing low pressure as a sign of possible leakage allows for timely investigation and maintenance, ensuring safety and efficiency in train operations.

Normal operating conditions would typically exhibit stable pressure readings within the designed parameters, thus indicating that the brake system is functioning correctly. Similarly, successful charge completion would reflect an increase in pipe pressure following charging, suggesting that the system is filling properly without leaks. Stable brake functions would generally correlate with consistent and expected pressure levels. Therefore, very low Straight Air pipe pressure distinctly flags potential leakage problems that require immediate attention to maintain system integrity and performance.
