If brakes are cut out on an end car after leaving the terminal, what must happen to the train?

The correct response indicates that if the brakes are cut out on an end car after leaving the terminal, it is necessary for the train to be removed from service at the next station. This requirement stems from safety protocols aimed at ensuring the safe operation of the train. Brakes are crucial for maintaining control over the train's speed and for stopping safely. Any compromise in the braking system can present significant safety risks, not only to passengers and crew but also to other trains and the railway infrastructure.

In the event that the brakes on an end car are not functioning, continuing the journey could lead to scenarios such as an inability to stop in an emergency, over-speeding, or unfavorable handling characteristics, particularly during turns or when navigating gradients. Therefore, removing the train from service allows for immediate attention to the mechanical issues, ensuring that repairs can be made before the train is put back into operation. This approach upholds safety standards and minimizes the risks associated with operating a train without fully functional braking systems.
