What role does the RWIC play regarding working limits?

The RWIC, or Roadway Worker In Charge, plays a critical role in ensuring the safety of workers within established working limits. When it comes to train movement through these working limits, the RWIC is specifically authorized to grant permission for trains to operate in those areas where workers are present. This responsibility is paramount in maintaining safety, as the RWIC must assess the situation, communicate with train crews, and ensure that all necessary precautions are in place before allowing any train movement.

This control helps to minimize the risk of accidents or incidents by ensuring that workers are fully aware of the status of any approaching trains. The RWIC's actions directly contribute to the safety of all personnel working on or near the tracks by managing the interaction between train operations and worker activities in a defined working limit.
