What is the expected position of the automatic brake valve on the BN 7042 when you first access it?

The expected position of the automatic brake valve on the BN 7042 when first accessed is typically referred to as the normal position. In this context, the term "normal position" indicates that the valve is set to its standard operational state, ready for use and not in a cut-out or reduced position. This ensures that the train's braking system is fully operational and can be engaged as needed during transit.

Having the automatic brake valve in this "normal position" allows for proper function and quick activation of the brakes if required, ensuring safety and responsiveness when managing the train's movements. Additionally, it is important to understand that a 20 psi brake pipe reduction, which suggests a specific reduction from the brake pipe pressure, is not a standard first-access position; it indicates a specific action that may be necessary under certain conditions but is not the baseline expectation upon initial inspection of the equipment.

Overall, recognizing that the valve should be in this state emphasizes the importance of maintaining the integrity and readiness of the train's air brake system for safe operations.
