If the electric feature of the electro-pneumatic brake fails, what is a likely outcome for the train?

When the electric feature of the electro-pneumatic brake fails, the likely outcome for the train is that it will stop beyond the usual stop. This situation arises because the electro-pneumatic braking system is designed to enhance braking efficiency by using both electrical and pneumatic forces to act on the train's brakes swiftly and effectively. If the electrical component fails, the brakes may not engage as intended, leading to a delayed response in braking action.

As a result, the train may not decelerate in time, causing it to overshoot the intended stopping point. The train relies on the coordination between the electrical signals and the pneumatic pressure, and a failure in the electric feature disrupts this balance. This means that, without sufficient braking force being applied at the right time, the train can continue coasting at a higher speed than necessary, ultimately resulting in an overshoot beyond the usual stop.

The other options, such as stalling indefinitely or increasing speed unexpectedly, do not accurately reflect the nature of a braking system failure in this context. While a failure may lead to challenges in stopping, it does not directly cause a sudden increase in speed or indefinite stalling. Hence, the correct understanding of the outcome of such a failure clearly points to overshooting the
