What is the preferred method of OTS in CTC territory?

The preferred method of OTS (Occupancy Tracking System) in CTC (Centralized Traffic Control) territory is track and time. This method involves assigning trains specific time windows for occupancy of sections of track, allowing for better management and coordination of train movements.

By utilizing track and time, dispatchers can effectively monitor train locations and ensure safe distances are maintained between trains. This approach minimizes the risk of collisions and enhances overall operational efficiency by allowing more trains to be dispatched on the same line safely. It also simplifies communication with train crews about their expected movement through certain segments of the track.

While other methods like "track and signal," "time and distance," and "district and route" may be relevant in different contexts or territories, track and time stands out in CTC territory for its effectiveness in managing train congestion and promoting safety through structured scheduling.
