How are safety zones defined in rail operations?

Answer: B — Designated areas near tracks where movement is restricted

Safety zones in rail operations are defined as designated areas near tracks where movement is restricted. This ensures the safety of passengers and workers by limiting access to these critical zones, where unauthorized individuals and equipment could potentially interfere with train operations or be exposed to hazards. These zones are strategically established to create a buffer between the trains and people, helping to prevent accidents and enhance overall safety in railway environments. While passenger rest areas, maintenance locations, and regions for trains to speed up serve various functions within rail operations, they do not specifically address the critical safety measures that safety zones are intended to enforce.
