What must be done after Train 520 experiences an emergency brake application while operating through a crossover?

After Train 520 experiences an emergency brake application while operating through a crossover, it is crucial to inspect the entire train. This action is essential to ensure the safety of both the train and its cargo. An emergency brake application can occur for several reasons, including mechanical failure or the presence of obstacles on the tracks. Inspecting the train allows the crew to identify any potential issues that could compromise safety or lead to further incidents.

Conducting a thorough inspection helps verify that all car couplings are intact, brakes are functioning properly, and there are no signs of derailment or damage. This process is critical in maintaining safety standards and ensuring that the train can continue its journey without additional risks.

In contrast, simply contacting the dispatcher again, resuming operation immediately, or waiting for further instructions may not adequately address the potential issues that could have arisen from the emergency braking. Safety protocols require a proactive approach, emphasizing the importance of inspection to safeguard against further complications.
