During foul time, who is responsible for ensuring no trains enter the working limits?

The RWIC, or Roadway Worker In Charge, holds the primary responsibility for ensuring that no trains enter the working limits during foul time. This role is critical because the RWIC is designated to oversee safety and coordinate activities on the work site, thereby ensuring that all safety protocols are strictly followed.

The RWIC’s responsibilities include monitoring the work area and communicating with train crews and dispatchers to establish and maintain safe working conditions. They are expected to have a comprehensive understanding of the safety protocols and the importance of maintaining control over access to the work limits.

In contrast, while other crew members, supervisors, and dispatchers play significant roles in the overall safety and operations, they do not have the direct authority or specific responsibilities assigned to ensure that the working limits remain clear of trains during foul time. Thus, the RWIC's role is central to the safety management in this context.
