When can working limits be established within a train's authority limits in CTC?

• A. When a train has authority to move in both directions
• B. When a train has non-joint track and time authority moving in one direction
• C. Whenever the dispatcher allows it
• D. When there is no traffic on adjacent tracks

Answer: (B)

Establishing working limits within a train's authority limits in Centralized Traffic Control (CTC) is pertinent to ensuring both operational safety and efficiency. When a train has non-joint track and time authority moving in one direction, it means the train does not share tracks with others, allowing the dispatcher to safely establish working limits without risk of conflicting movements. This scenario helps maintain control over a specific segment of track, ensuring that maintenance operations or other activities can occur without jeopardizing the train's safety or efficiency. By having non-joint track, the risk is mitigated since there are no simultaneous movements from another train on that same track segment. The dispatcher can then designate working limits within those parameters to facilitate the necessary work without delays or hazards.
