Which term describes a location from which an interlocking is operated?

• A. Main Track
• B. Interlocking Signals
• C. Interlocking Station
• D. Marker

Answer: (C)

Interlocking station is the location from which an interlocking is operated. An interlocking is a coordinated system of signals and switches designed to prevent conflicting movements, and it is controlled from a dedicated place—the interlocking station (sometimes called an interlocking tower on older systems). This is where the operator uses the control panel or levers to set routes and lock signals and switches as trains move through the interlocking area. The other options don’t describe where the control happens: the main track is the actual track, not the control point; interlocking signals are the devices within the interlocking; and a marker is a sign or reference point, not the place of operation.
