Who is primarily responsible for issuing route clearances and ensuring the signal system reflects the authorization?

• A. Conductor
• B. Safety Manager
• C. Dispatcher
• D. Control Room Operator

Answer: (C)

Granting movement on a specific route and making sure the signals reflect that permission is the dispatcher's responsibility. The dispatcher receives requests, checks track occupancy and potential conflicts, and issues a route clearance that designates which route is authorized. The signaling system, including interlockings and track circuits, is then set to show the agreed clearance, guiding trains with the correct signal indications and preventing unsafe movements. The conductor operates the train under that authority, but does not issue the route clearances. The safety manager handles safety policy and audits, while the control room operator monitors systems and can support operations but does not grant movement authorization.
