What is the standard brake pipe pressure range for M-7 trains?

The standard brake pipe pressure range for M-7 trains is typically between 120 to 150 PSI. This range is critical for the proper functioning of the air brake system, ensuring that the brakes operate effectively to maintain safe stopping distances and performance.

Maintaining the brake pipe pressure within this specified range is essential for the system to properly respond to commands from the engineer, allowing for precise control over braking actions and minimizing the risk of brake failures. It is vital for operators to regularly monitor and adjust the brake pipe pressure to fall within this range to ensure safe and efficient train operation.
