What is the term for the practice of operating in series speed following a power restoration?

The term "reduced speed" refers to the practice of operating a train at a lower speed following a power restoration, especially in situations where safety protocols necessitate caution. This procedure is crucial for ensuring that drivers can assess the track and signals adequately after a disruption, such as a power outage.

In the context of train operations, reduced speed allows for a safe approach to potentially dangerous conditions that may have arisen during the interruption of service. It enables operators to conduct necessary inspections or respond to issues that may have occurred during the power loss, ensuring passenger safety as they transition back to normal operational speeds.

Other terms such as "conventional speed," "standard operational speed," and "pre-normal speed" do not specifically capture this cautious approach to speed management after a restoration of service. They imply either a regular operating condition or a state that lacks the caution required post-disruption. Thus, "reduced speed" accurately reflects the necessary protocol in these scenarios.
