What should be checked when there is no air pressure reaching the rear of your train during the Initial Terminal Air Brake Test?

When there is no air pressure reaching the rear of your train during the Initial Terminal Air Brake Test, it is essential to check that the air hoses are properly coupled and that the angle cocks are positioned correctly. This is crucial because proper coupling of the air hoses ensures a continuous air supply throughout the train. If the hoses are not securely connected, or if the angle cocks are in the wrong position, it can prevent the air from flowing, leading to a lack of pressure at the rear.

By checking these components, you can diagnose the problem accurately and take the necessary steps to restore proper air flow. Ensuring that the air hoses are coupled and angle cocks are aligned correctly is a fundamental safety check that helps guarantee the reliability of the train's braking system.
