What is the definition of ‘protecting train’ in NORAC terms?

• A. A train or crew assigned to safeguard a work location or obstructed section of track.
• B. Any train in service.
• C. A train that operates at high speed.
• D. A train that is in quarantine.

Answer: (A)

The main idea is that a protecting train is a train or crew that is specifically assigned to safeguard a work location or an obstructed section of track. When maintenance or inspections are happening on or near the rails, this designated train provides the required protection for workers and for the work area by signaling and positioning itself to warn or stop approaching trains. It creates a controlled safe zone around the work site, ensuring trains don’t unexpectedly enter the protected area and that workers have a clear, protected path.

That’s why this definition fits best: it describes a specialized role focused on protection rather than all trains in service, high-speed operation, or something unrelated like quarantine.
