What is the requirement for a train to proceed from a Stop indication in CTC territory?

In CTC (Centralized Traffic Control) territory, a train must receive authorization from the control operator to proceed from a Stop indication. This requirement is essential for maintaining the safety and efficiency of train operations. The control operator oversees the movement of trains and ensures that they are cleared to proceed only when the track ahead is safe and free from conflicting movements.

Obtaining authorization helps prevent collisions and ensures that trains are moving in a controlled manner based on the current operational conditions. In CTC systems, communications are typically established through clear protocols that include confirming the signal aspects and ensuring that all safety measures are met before a train can safely continue its journey from a stop signal.
