What should be done if brake pipe pressure is below the specified minimum before moving SMEE cars?

If brake pipe pressure is below the specified minimum before moving SMEE (Sliding-Mean Electric Emphasis) cars, the appropriate action is to delay until the pressure is restored. This is crucial for ensuring safety on the train. Brake systems are designed to operate within specific pressure parameters to effectively manage stopping distances and train control during transit. Insufficient brake pipe pressure can lead to inadequate braking performance, increasing the risk of accidents or train incidents.

Delaying operations until the pressure reaches the minimum required level ensures that the braking system is fully functional. It is imperative that safety protocols are followed meticulously in rail operations, and operating a train with insufficient brake pressure could severely compromise the safety of both passengers and crew, as well as the integrity of rail operations. Thus, restoring proper brake pipe pressure is a fundamental requirement before proceeding with any movement of the train.
