Explanation:
If a brake pipe rupture occurs when a train is coming to a stop, the train operator will have no control of the brakes. The brake pipe is an essential part of the train's braking system, and a rupture would result in a loss of pressure and the inability to apply or release the brakes. In such a situation, the train operator would need to use the emergency brake as a last resort to bring the train to a stop.
