On a non-controlled track, what type of working limit is applied?

When working on a non-controlled track, the application of an inaccessible track working limit is appropriate to ensure the safety of roadway workers. This type of limit provides clear guidelines that prevent any unauthorized access or use of the track while workers are present, effectively protecting them from moving trains and other potential hazards.

Inaccessible track working limits are established to maintain a designated area where work can be performed without interference. This approach is vital in non-controlled environments because these tracks do not have signals or restrictions that would automatically hinder train movements. Therefore, designating the area as inaccessible helps to keep workers safe from unpredictable train operations.

The other options do not align with the requirements for non-controlled tracks. For example, exclusive track occupancy allows for a specific track segment to be used solely by roadway workers but would require a more controlled environment. Foul time and continuous track access provide different levels of operational control that are not feasible on non-controlled tracks where the priority is to prevent access altogether.
