The Dispatcher must properly line the route for the movement of track cars at interlockings and controlled points. Signals must not be displayed for movement to?

• A. Main Tracks
• B. Yard Tracks
• C. Secondary Tracks
• D. ABS OR DCS Tracks

Answer: (D)

When the dispatcher lines a route at interlockings and controlled points, signals are used to authorize movements along signaled routes. But some tracks aren’t governed by the same signaling scheme—ABS and DCS tracks operate under their own protection and do not receive the standard interlocking signal indications for track-car movements. Displaying signals for a movement onto those tracks could mislead the operator and conflict with the track’s separate protection system. Therefore, signals must not be displayed for movement to ABS or DCS tracks. Movements to other track types like main, yard, or secondary tracks are subject to normal signaling, so displaying signals in those cases is appropriate.
