Who is authorized to permit the movement of trains through working limits?

The correct answer, the Roadway Worker In Charge (RWIC), is essential in the context of roadway worker protection as the individual designated to ensure the safety of workers in a designated working limit on the track. The RWIC is responsible for coordinating the protection of roadway workers and managing the safe movement of trains through the working limits. This includes issuing specific instructions related to train movements and ensuring all safety protocols are followed.

The role of the RWIC is pivotal as this person has undergone specific training and is familiar with operational safety procedures, making them qualified to assess situations and determine when it is safe for trains to proceed through areas where workers are present. This authority is crucial in preventing accidents and ensuring that both workers and trains operate safely within the confines of the working limits.

Other roles, such as a station manager or track inspector, do not typically hold the authority to permit train movements through working limits. Similarly, while an on-site engineer may have responsibilities pertaining to the work and operations on the site, they are not designated with the authority to control train movements in this context.
