Protection against trains in both directions has been provided in ABS, DCS, or in Interlockings by whom?

• A. The Dispatcher
• B. The Station Master
• C. Crew members
• D. Maintenance supervisor

Answer: (A)

Protection against trains in both directions is provided by the Dispatcher. In ABS, DCS, and interlockings, the Dispatcher has the authority to authorize movements, set routes, and ensure the signaling and interlocking logic protect against opposing or conflicting trains. This centralized control keeps movements coordinated across bidirectional tracks, preventing collisions.

The other roles aren’t responsible for this level of protection. A Station Master handles station operations locally rather than overseeing bi-directional movement across signaling systems. Crew members operate trains under the protections in place but don’t grant or enforce movement protection themselves. A maintenance supervisor isn’t involved in directing train movement protection.
