What contributes to determining speed limitations as prescribed by Rule 562?

The determination of speed limitations under Rule 562 primarily revolves around the authority received. This authority typically comes from a dispatcher or higher operational authority, allowing train crews to proceed at specific speeds based on the operational context and safety considerations.

Rule 562 is designed to ensure safe operations in various circumstances, and the dispatcher communicates the authority to the train crew regarding how fast they can go. This authority takes precedence and is tailored to the specific situation at hand, allowing for adjustments in speed based on factors that may be unique to the particular train's operation, route conditions, or any temporary restrictions that may be in place.

Additionally, while weather conditions, type of cargo, and signal indications are important factors that can influence overall train operations, they do not directly dictate the speed limits as established under Rule 562. Instead, it is the communicated authority that ultimately governs how the train should proceed in compliance with safety regulations and operational standards.
