When may a solid loaded bulk commodity train proceed without inspection after an emergency brake application?

The option stating that a solid loaded bulk commodity train may proceed without inspection after an emergency brake application if brake pipe pressure is being restored at the rear of the train is correct because it indicates that the braking system is returning to normal operation. When a train experiences an emergency brake application, it is crucial to ensure that the braking pressure is stable and that the train can be safely restarted. If brake pipe pressure restoration is underway, it suggests that the issue causing the emergency brake application is being resolved, and the train can proceed safely without needing a full inspection.

This protocol allows for efficiency in train operations while maintaining safety standards. In cases where pressure is being restored, it indicates that the systems are still intact, providing a level of assurance that a dangerous situation is being mitigated.
