In 562 territory, how must MDZs operate at signals displaying Stop and Proceed or Restricting?

In 562 territory, signals displaying Stop and Proceed or Restricting require trains, including those operating under Modified Dispatcher Zones (MDZs), to stop at the signal. This protocol is in place to ensure safety and compliance with the established operating rules, as these signal indications imply that the train must prepare for potential hazards or restricted track conditions ahead. By stopping at these signals, the train crew has the opportunity to assess the situation, receive updated instructions, or ensure that it does not proceed until it is safe to do so.

Operationally, this approach minimizes risks by allowing the crew to confirm the safety of the route and to comply with any necessary precautions before continuing. It is essential for maintaining the safety of both the train and surrounding rail traffic. Other choices imply actions that could lead to unsafe conditions, as they either promote unauthorized movement or fail to address the need for caution indicated by the restrictive signals.
