Under what condition can the train dispatcher grant joint or overlapping authorities?

The ability for a train dispatcher to grant joint or overlapping authorities hinges on the implementation of proper safeguards. Safeguards are critical in ensuring the safety and efficiency of train operations, particularly when two trains have overlapping movements.

The dispatcher must exercise caution and adhere to established protocols to minimize risks when allowing joint authorities. These safeguards could include ensuring that the trains involved are adequately communicated with, confirming their locations, speeds, and routes, and using signal systems effectively to avoid potential collisions.

By requiring proper safeguards before granting overlapping authorities, the dispatcher upholds safety standards and regulatory compliance, ultimately protecting both the trains and crew involved in the operation.
