In 251 Territory, how is a train expected to operate when encountering a restricting signal?

When a train encounters a restricting signal in 251 Territory, it is expected to operate at Restricted Speed. This means the train must be prepared to stop short of any obstruction, including other trains, and be able to comply with any restrictions set by the signal. Operating at Restricted Speed allows the engineer to maintain control of the train while navigating potentially hazardous conditions, ensuring safety as the train approaches areas where the track or signal indications might require caution.

The key characteristic of Restricted Speed is that it requires the engineer to be alert and prepared for any unexpected conditions ahead, such as track maintenance or other trains on the same track. This protocol is crucial for maintaining safety standards in rail operations, particularly in areas where visibility may be limited or additional caution is necessary.
