In what scenario can a loaded unit coal train proceed without inspection after an emergency brake application?

• A. When the train has more than 200 cars
• B. If the train has no pusher and air pressure is increasing
• C. If the train is moving through a turnout or crossover
• D. When train speed is above 50 MPH

Answer: (B)

A loaded unit coal train can proceed without inspection after an emergency brake application if there is no pusher involved and air pressure is increasing. This situation indicates that the train's braking system is functioning effectively, and there is a possibility that the emergency brake application was not due to any issue with the train itself, but rather an external factor that does not compromise the integrity of the train's operation. When there is no pusher, it means that the driving force of the train is coming solely from the lead locomotives, which helps maintain control over the braking system. Additionally, if air pressure is increasing, it typically suggests that the train's air brake system is recovering properly after the emergency application, showing that all cars in the train are still intact and connected correctly. Therefore, under these conditions, it is safe to continue the journey without further inspection. Other scenarios, such as those involving excessive train length, external speed limits, or navigation through turnouts, might impose more stringent inspection requirements to ensure safety, making them not applicable for proceeding without an inspection in the context of emergency brake applications.
