If a train has passed a distant signal and stops for any reason, what is the maximum speed it can proceed?

When a train has passed a distant signal and subsequently stops, the maximum speed at which it can proceed is set to ensure the safety of the train's movement. The rule specifies that the speed limit is established to allow for safe operations in the event of needing to stop again or encountering any unforeseen circumstances further down the track.

Usually, this maximum speed is defined in the operating rules to ensure that the train can still respond effectively to conditions ahead, such as adverse signals or other train movements. The limit is calibrated to maintain control and safety while enabling efficient train operations.

In this context, the specified maximum speed of 30 mph allows trains to advance from a stopped position after a distant signal without sacrificing safety while still promoting efficiency. This speed threshold reflects considerations for factors like stopping distance, the condition of the track, and typical signal indications.

The selections that provide lower speeds do not align with the necessary safety and operational standards for this scenario, which makes the selection of 30 mph the most suitable and correct choice.
