If a defect detector indicates dragging equipment and an obstruction prevents you from getting to the indicated axle, what should you do?

• A. Walk as much of the train as possible, then move no more than 5 MPH to complete the inspection.
• B. Stop the train and wait for a supervisor to arrive.
• C. Return to the previous yard and file a report.
• D. Immediately cut out the affected car.

Answer: (A)

When a defect detector flags dragging equipment, the priority is to identify which car is causing the drag while keeping everyone safe. If the axle you need to inspect is blocked, you still must complete the inspection as far as you can. The best approach is to walk along as much of the train as possible to visually check the axles and brake rigging you can reach. Then, you should continue the inspection by moving the train at a very slow, controlled pace—no more than 5 mph—so you can observe for signs of dragging while maintaining safety and control. This lets you gather enough information to determine the problem without insisting on access that’s blocked or delaying action unnecessarily.

Stopping to wait for a supervisor, returning to the yard to file a report, or cutting out a car without properly identifying the drag would either waste time or create unnecessary risk. Moving slowly after doing what you can to inspect the train strikes the right balance between safety, efficiency, and getting to the root of the issue.
