Who is the signaller on a rail network?

• A. The person in charge of the working of points or signals
• B. A trainee
• C. A station announcer
• D. A maintenance supervisor

Answer: (A)

Controlling signals and points is what keeps train movements safe. The signaller is the person who operates the signals and the routing of trains at a signal box or control center. They set routes by adjusting points and signaling devices, ensure the correct indications are shown to train drivers, and coordinate with drivers to authorize moves. They work within interlocking rules to prevent conflicting routes and maintain safe train separations. In short, the signaller is the person in charge of making sure signals and points function correctly to guide trains along safe routes. A trainee is someone learning the job, not in charge. A station announcer handles passenger announcements. A maintenance supervisor oversees upkeep of track and equipment, not the signaling operation.
