What speed defines limited speed for passenger trains?

Limited speed for passenger trains is defined as a maximum speed of not exceeding 45 mph. This designation is crucial for ensuring safe operations in areas where there may be restrictions or hazards, such as near work zones, stations, or when approaching signals that may require caution. Operating at limited speed allows train crews to have increased reaction time and control, contributing to overall safety and efficiency in train operations.

While the other speed limits provided are important in different contexts, they do not align with the established definition for limited speed for passenger trains, which is precisely set at 45 mph. Understanding this speed limit is vital for any trainee as it relates to adherence to safety protocols and operational standards within the rail system.
