Before leaving the engine leaves its Initial terminal, which equipment must be operational?

• A. Auxiliary lights.
• B. Headlights.
• C. Air brakes.
• D. Windshield wipers.

Answer: (A)

Auxiliary lights must be operational when leaving the initial terminal because they provide essential visibility and signaling in yard operations, especially in low light or congested environments. These lights (including ditch lights and other marker lights) alert yard workers and approaching trains that the locomotive is in service and moving, helping prevent collisions and miscommunication. While headlights, air brakes, and windshield wipers are important for safe operation, the rule tested here emphasizes that the auxiliary lights be functioning at departure from the terminal.
