Traffic, Normal Direction of:

Traffic, Normal Direction of:

• A. On double track, the normal direction is to the right unless otherwise directed by Rules, Bulletins, Procedures or as instructed by the Controller.
• B. The normal direction varies by hour.
• C. In the direction of increasing mileposts.
• D. The normal direction is determined by the conductor.

Answer: (A)

On double track, trains normally run on the right-hand side. This convention keeps traffic predictable, makes signal visibility consistent, and simplifies safe passing and meet operations. You follow that right-hand running unless Rules, Bulletins, Procedures, or the Controller instruct otherwise for a specific situation, such as maintenance or special movements. The other ideas don’t fit because this normal direction isn’t set by the hour, isn’t determined by mileposts, and while the conductor can issue temporary directions, the standard baseline direction on double track is right-hand running.
