What essential information must a dispatcher provide before getting OOS authority, Foul Time, or Local Control?

The essential information a dispatcher must provide before obtaining Out-of-Service (OOS) authority, Foul Time, or Local Control is the conditions affecting tracks on hold, including barricade and equipment locations. This information is critical for ensuring safety and coordination in train operations.

When a dispatcher requests OOS authority or issues Foul Time, it is crucial to communicate the status of the tracks involved and any potential hazards present. Providing details about barricades, work zones, or any equipment located on or near the tracks helps to ensure that all train movements can be conducted safely. It allows train crews and other personnel to understand the extent of any restrictions or safety measures in place, reducing the risk of accidents or conflicts on the tracks.

While the other options contain relevant information for various operational scenarios, they do not encompass the immediate safety concerns that necessitate the control measures mentioned. The list of train engineers on duty, train schedules, and information on past delays may assist in broader operational logistics, but they do not directly impact the dispatcher’s immediate responsibility of communicating safety conditions prior to gaining OOS authority, Foul Time, or Local Control.
