What actions should the crew take for positive train identification during a train meet?

The correct choice involves several essential actions that the crew should take for positive train identification during a train meet. Establishing positive train identification is crucial for ensuring the safety and efficiency of train operations.

Visually identifying the train station can help the crew orient themselves with their location, but it doesn’t specifically pertain to identifying the train. Establishing positive radio contact is important for communication between crews and can aid in coordinating movements and confirming identification. However, confirming the lead locomotive number and recording its identity is the most direct method of ensuring that the crew is aware of which train they are dealing with. This helps to prevent any potential miscommunication or accidents that could arise from mistaking one train for another.

Considering the combination of these actions, they collectively enhance safety and operational efficacy during a train meet, making "all of the above" the most comprehensive and accurate answer. By combining visual identification, radio communication, and verification of the locomotive’s identity, crews can ensure a thorough confirmation process, which is critical in real-world operations where precision is paramount.
