What is the recommended procedure for a minor brake pipe leak during descent on a grade?

Maintaining speed and monitoring the situation is the recommended procedure for a minor brake pipe leak during descent on a grade. This approach allows the crew to keep the train under control while assessing the impact of the leak. By closely observing the train's performance and the status of the brake system, the crew can make informed decisions about what actions to take next.

It's crucial to recognize that minor leaks may not significantly affect braking power immediately, allowing for continued safe operation. The crew should keep an eye on the brake pipe pressure and any changes in the train’s speed, which helps ensure that any necessary adjustments can be made swiftly and effectively.

Ignoring the leak, increasing the throttle, or applying emergency brakes might not be appropriate actions. Ignoring the leak could lead to a more severe problem if the leak worsens. Compensating with more throttle may increase the danger and lead to an inability to slow or stop the train effectively. Applying emergency brakes immediately can cause excessive wear on the braking system or derailment under certain circumstances, so it's better to monitor the situation carefully and respond based on the observation of the train's behavior.
