Which term is a place from which an interlocking is operated?

• A. Station
• B. Interlocking Station
• C. Block-Limit Station
• D. Block Station

Answer: (B)

Interlocking systems coordinate signals and track switches so trains don’t move into conflicting routes at junctions. The place where that interlocking is operated is called the interlocking station. It’s the control point, historically a signal tower and now often a computerized center, where operators set routes and lock points to ensure safe movements through the junction. The other terms describe general stations or block boundaries rather than the specific control location for an interlocking.
