After coupling two locomotives or cars, what must be verified?

• A. Security of the connection, proper air line connections, adequate brake charge, and protection.
• B. Security of the connection alone.
• C. The direction of travel.
• D. The color of the couplers.

Answer: (C)

The key idea is setting up safe movement by confirming which end of the train will lead and which direction you will move in. When two locomotives or cars are coupled, knowing the direction of travel tells you which locomotive and controls will drive the train and ensures you apply throttle and brakes from the correct end. This prevents moving the train in the wrong direction or into signals, switches, or other equipment. In practice, you’d also verify the physical connection and that the air brake system is ready, but establishing the intended direction of travel is the essential step before moving.
