With regard to track switches, what is required as part of securing for a break?

Answer: B — Secure them in the required position as part of procedures.

Securing for a break means locking the switch in the position specified by your operating procedures. This ensures the switch cannot move unintentionally while the crew is away, keeping the intended route safe and clear for any approaching trains. The required position is defined by the rules for the task, and a proper locking device or method is used to hold it there. Leaving the switch in whatever position it was found creates a risk of movement from wind, vibration, or train impact, which could misroute equipment or cause a derailment. Turning off or disabling the switch isn’t how this is handled in normal operations, and notifying someone to adjust it later wouldn’t secure the switch now or comply with procedures.
