What is the maximum allowable speed a train can maintain after passing a distant signal and reducing speed?

The maximum allowable speed a train can maintain after passing a distant signal and reducing speed is 30 mph. This speed limit is in place to ensure safety as the train approaches a signal indication, allowing the train crew sufficient time to react to any subsequent signals while maintaining a manageable speed. The designation of 30 mph reflects operational practices that recognize both the need for caution in high-traffic areas and the ability for trains to maintain efficient service.

Adhering to this speed limit after passing a distant signal helps in reducing the risk of incidents that could arise from higher speeds, particularly when the next signal could indicate a stop or caution. Understanding this speed limit is crucial for ensuring the safe operation of trains within the network and aligns with protocol set out in the operating rules.
