What should crew members do when inspecting a passing train when the train is stopped?

Crew members are trained to prioritize safety when inspecting a passing train, especially when it is stopped. Dismounting on the side opposite the approaching train is the safest practice, as it minimizes the risk of injury from any potential hazards, such as debris or another train that may be passing close by. This procedure allows crew members to maintain a safe distance from the trackside and avoid being in the path of oncoming rail traffic.

The other options present scenarios that lack adequate safety measures. For instance, inspecting from the cab of the engine does not provide a clear view of the passing train and may also limit the crew's ability to effectively identify any issues or hazards. Crossing adjacent tracks for a better view exposes crew members to unnecessary risks, as trains can come from multiple directions. Remaining seated until the train moves does not allow for any inspection of the stopped train and does not contribute to situational awareness. Thus, choosing to dismount on the side opposite the approaching train is the most prudent and safety-conscious action.
