During a Class I Brake Test - Initial Terminal Inspection, which of the following must be confirmed about the train's brakes?

The correct answer involves the requirement that brakes must be released on each car during the Class I Brake Test - Initial Terminal Inspection. This step is crucial to ensure that the brakes are functioning properly when applied throughout the entire train. When the brakes are released, it allows the inspection personnel to verify that the braking system is operational by checking for proper release and ensuring there are no sticking or malfunctioning components.

By confirming that the brakes are released on each car, it sets the stage for subsequent procedures, including the application of the brakes and measuring the train's stopping capabilities. Such thorough checks help prevent potential safety hazards during operation, making it essential for train integrity and operability.

This approach emphasizes the importance of a collective assessment of the entire train rather than focusing on individual cars or specific sections. Each car's braking system must be engaged in the inspection process to ensure they all work in unison for safe operations. Thus, confirming that brakes are released on all cars is a fundamental part of the procedure.
