Under Lifebook T-6, when may employees ride the platform of a tank car?

• A. Only if supervised
• B. When it's the trailing platform on the trailing car of the cut and they are pulling the track out
• C. On any platform at any time
• D. Only on the leading platform on the leading car

Answer: (B)

The situation being tested is about when it’s allowed to ride the platform on a tank car under Lifebook T-6. The safety rule here is that riding on the exterior of equipment is tightly restricted and only permitted for a very specific operation.

Why this option is the best: riding on the trailing platform of the trailing car of the cut, and only while the crew is pulling the track out, places you in a position that minimizes exposure to hazards. From the trailing end, you can monitor the work from behind, stay out of the path of the moving track being removed, and keep clear of the leading car’s end where shifting or unexpected movements are more risky. This setup also helps maintain communication with the locomotive crew and other crew members while keeping you shielded from the active work area.

In other contexts—on the leading platform, on any platform, or without a specific controlled operation—the risks are higher and the rule generally prohibits riding. That’s why the trailing-end, trailing-car scenario during track removal is the defined, permitted exception.
